V
data-acquisition systems. It has very low noise at
2 nV/√Hz, and extremely low harmonic distortion of
–76 dBc HD2 and –88 dBc HD3 at 70 MHz with
2 Vpp, G = 14 dB, and 100 Ω load. Slew rate is very
high at 5100 V/μs and with settling time of 5.5 ns to
1% (2 V step) it is ideal for pulsed applications. It is
designed for minimum gain of 6 dB.

Minimum Gain of 2 V/V (6 dB)
Bandwidth: 1.1 GHz (Gain = 6 dB)
Slew Rate: 5100 V/μs
1% Settling Time: 5.5 ns
HD2: –76 dBc at 70 MHz
HD3: –88 dBc at 70 MHz
To allow for dc coupling to ADCs, its unique output
common-mode control circuit maintains the output
common-mode voltage within 5 mV offset (typical)
from the set voltage, when set within ±0.5 V of
mid-supply. The common-mode set point is set to
mid-supply by internal circuitry, which may be
over-driven from an external source.
OIP2: 84 dBm at 70 MHz
OIP3: 42 dBm at 70 MHz
Input Voltage Noise: 2 nV/√Hz (f > 10 MHz)
Noise Figure: 21.8 dB (50 Ω System, G = 6 dB)
Output Common-Mode Control
5 V Power Supply Current: 39.2 mA
Power-Down Capability: 0.65 mA
Rad-Tolerant: 150 kRad (Si) TID
QML-V Qualified, SMD 5962-07222
The THS4511 is a high-performance amplifier that
has been optimized for use in 5 V single-supply data
acquisition systems. The output has been optimized
for best performance with its common-mode voltages
set to mid-supply, and the input has been optimized
for performance over a wide range of common-mode
APPLICATIONS
input voltages. High performance at
a
low
power-supply voltage enables single-supply 5 V
data-acquisition systems while minimizing component
count.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

TEST CIRCUITS
The output is probed using a high-impedance
differential probe across the 100 Ω resistor. The gain
is referred to the amplifier output by adding back the
6 dB loss due to the voltage divider on the output.
The THS4511 is tested with the following test circuits.
For simplicity, the power supply decoupling is not
shown – see the layout in the application information
section for recommendations. Depending on the test
conditions, component values are changed per the
following tables, or as otherwise noted. The signal
generators used are ac coupled 50 Ω sources, and a
0.22 μF capacitor and a 49.9 Ω resistor to ground are
inserted across RIT on the alternate input to balance
the circuit.

Note: The gain setting includes 50 Ω source

A signal generator is used as the signal source, and
the output is measured with a spectrum analyzer. The
output impedance of the signal generator is 50 Ω. RIT
and RG are chosen to impedance-match to 50 Ω and
to maintain the proper gain. To balance the amplifier,
a 0.22 μF capacitor and 49.9 Ω resistor to ground are
inserted across RIT on the alternate input.

A low-pass filter is inserted in series with the input to
reduce harmonics generated at the signal source.
The level of the fundamental is measured, then a
high-pass filter is inserted at the output to reduce the
fundamental so that it does not generate distortion in
the input of the spectrum analyzer.
Note: The total load includes 50 Ω termination by
the test equipment. Components are chosen to
achieve load and 50 Ω line termination through a
1:1 transformer.
The transformer used in the output to convert the
signal from differential to single ended is an
ADT1-1WT. It limits the frequency response of the
circuit so that measurements cannot be made below
approximately 1 MHz.
Due to the voltage divider on the output formed by
the load component values, the amplifier's output is
attenuated. The column Atten in Table 2 shows the
attenuation expected from the resistor divider. When
using a transformer at the output as shown in
Figure 31, the signal will see slightly more loss, and
these numbers will be approximate.

operational amplifier. Note RS and RIT are added to
the alternate input from the signal input to balance
the amplifier. One resistor that is equal to the
combined value RI = RG + RS||RIT can be placed at
the alternate input.
The output common-mode voltage is set by the
voltage at the CM pin(s). The internal common-mode
control circuit maintains the output common-mode
voltage within 5 mV offset (typical) from the set
voltage, when set within 0.5 V of mid-supply. If left
unconnected, the common-mode set point is set to
mid-supply by internal circuitry, which may be
over-driven from an external source. Figure 37 is
representative of the CM input. The internal CM
circuit has about 700 MHz of –3 dB bandwidth, which
is required for best performance, but it is intended to
be a dc-bias input pin. Bypass capacitors are
recommended on this pin to reduce noise at the
output. The external current required to overdrive the

Table 3 is a modification of Table 1 to add the proper
values with RPD assuming VS+ = 3.75 V, a dc-coupled
50 Ω source impedance, and setting the output
common-mode voltage to mid-supply.
The THS4511 is optimized to work in systems using
5 V single supplies, and the characterization data
presented in this data sheet was taken with 5 V
single-supply inputs. For ac-coupled systems or
dc-coupled systems operating with supplies less than
5 V and greater than 3.75 V, the amplifier input
common-mode range is maximized by adding
pull-down resistors at the device inputs. The
pull-down resistors provide additional loading at the
input, and lower the common-mode voltage that is fed
back into the device input through resistor RF.
Figure 38 shows the circuit configuration for this
mode of operation where RPD is added to the
dc-coupled circuit to avoid violating the VICR of the

originating from a HDTV 720p video system. The
input signal includes a tri-level sync (minimum level at
–0.3 V) and the portion of a video signal with
maximum amplitude of 0.7 V. Although the buffer
draws its power from a 5 V single-ended power
supply, internal level shifters allow the buffer to
support input signals, which are as much as –0.3 V
below ground. This allows maximum design flexibility
while maintaining a minimum parts count. Figure 42
shows the differential output of the buffer. Note that
the DC-coupled amplifier can introduce a DC offset
on a signal applied at its input.

THS4511 + ADS5500 Combined Performance
THS4511 + ADS5424 Combined Performance
The THS4511 is designed to be a high-performance
drive amplifier for high-performance data converters
like the ADS5500 14 bit 125 MSPS ADC. Figure 43
shows a circuit combining the two devices. The
THS4511 amplifier circuit provides 10 dB of gain and
converts the single-ended input signal to a differential
output signal. The default common-mode output of
the THS4511 (2.5 V) is not compatible with the
required common-mode input of the ADS5500
(1.55 V), so dc-blocking capicitors are added (0.22
µF). Note that a biasing circuit (not shown in
Figure 43) is needed to provide the required
common-mode, dc-input for the ADS5500. The 100 Ω
resistors and 2.7 pF capacitor between the THS4511
outputs and ADS5500 inputs, along with the input
capacitance of the ADS5500, limit the bandwidth of
the signal to 115 MHz (–3 dB). For testing, a signal
generator is used for the signal source. The
generator is an ac-coupled 50 Ω source. A band-pass
filter is inserted in series with the input to reduce
harmonics and noise from the signal source. Input
termination is accomplished via the 69.8 Ω resistor
and 0.22 μF capacitor to ground in conjunction with
the input impedance of the amplifier circuit. A 0.22 μF
capacitor and 49.9 Ω resistor are inserted to ground
across the 69.8 Ω resistor and 0.22 μF capacitor on
the alternate input to balance the circuit. Gain is a
function of the source impedance, termination, and
348 Ω feedback resistor. See Table 1 for component
values to set proper 50 Ω termination for other
common gains.
Figure 44 shows the THS4511 driving the ADS5424
ADC.
The THS4511 amplifier provides 10 dB of gain,
converts the single-ended input to differential, and
sets the proper input common-mode voltage to the
ADS5424. Input termination and circuit testing is the
same as described above for the THS4511 +
ADS5500 circuit.
The 225 Ω resistors and 2.7 pF capacitor between
the THS4511 outputs and ADS5424 inputs (along
with the input capacitance of the ADC) limit the
bandwidth of the signal to about 100MHz (–3dB).
When the THS4511 is operated from a single power
supply with VS+ = 5 V and VS- = ground, the 2.5 V
output common-mode voltage is compatable with the
recommended value of the ADS5424 input
common-mode voltage (2.4 V).

Layout Recommendations
5. Two 10 μF and two 0.1 μF power-supply
decoupling capacitors should be placed as near
the power-supply pins as possible.
It is recommended to follow the layout of the external
components near the amplifier, ground plane
construction, and power routing of the EVM as
closely as possible. General guidelines are:
6. Two 0.1 μF capacitors should be placed between
the CM input pins and ground. This limits noise
coupled into the pins. One each should be placed
to ground near pin 4 and pin 9.
1. Signal routing should be direct and as short as
possible into and out of the operational amplifier
circuit.
7. It is recommended to split the ground pane on
layer 2 (L2) as shown below and to use a solid
ground on layer 3 (L3). A single-point connection
should be used between each split section on L2
and L3.
2. The feedback path should be short and direct
avoiding vias.
3. Ground or power planes should be removed from
directly under the amplifier’s input and output
pins.
8. A single-point connection to ground on L2 is
recommended for the input termination resistors
R1 and R2. This should be applied to the input
gain resistors if termination is not used.
4. An output resistor is recommended on each
output, as near the output pin as possible.
