The HFA1145 is a high speed, low power current feedback
amplifier built with Intersil’s proprietary complementary
bipolar UHF-1 process.
This amplifier features a TTL/CMOS compatible disable
control, pin 8, which when pulled low reduces the supply
current and forces the output into a high impedance state.
This allows easy implementation of simple, low power video
switching and routing systems. Component and composite
video systems also benefit from this op amp’s excellent gain
flatness, and good differential gain and phase specifications.
• Pb-Free Plus Anneal Available (RoHS Compliant)
Multiplexed A/D applications will also find the HFA1145
useful as the A/D driver/multiplexer.
Applications
The HFA1145 is a low power, high performance upgrade for
the CLC410.
• Flash A/D Drivers
• Video Switching and Routing
• Professional Video Processing
• Video Digitizing Boards/Systems
• Multimedia Systems

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.

NOTES:
1. Output is short circuit protected to ground. Brief short circuits to ground will not degrade reliability, however continuous (100% duty cycle) output
current must not exceed 30mA for maximum reliability.
2. θ is measured with the component mounted on an evaluation PC board in free air.

Capacitive loads, such as an A/D input, or an improperly

possible oscillations. In most cases, the oscillation can be
The die version of the HFA1145 provides the user with a GND
pad for setting the disable circuitry GND reference. With
symmetrical supplies the GND pad may be left unconnected, or
tied directly to GND. If asymmetrical supplies (e.g. +10V, 0V)
are utilized, and TTL compatibility is desired, die users must

Picking a point above or to the right of the curve yields an
overdamped response, while points below or left of the curve
indicate areas of underdamped performance.
The HFA1145 utilizes a quasi-complementary output stage to
achieve high output current while minimizing quiescent supply
current. In this approach, a composite device replaces the
traditional PNP pulldown transistor. The composite device
switches modes after crossing 0V, resulting in added distortion
for signals swinging below ground, and an increased
undershoot on the negative portion of the output waveform
(See Figures 5, 8, and 11). This undershoot isn’t present for
small bipolar signals, or large positive signals. Another artifact
of the composite device is asymmetrical slew rates for output
signals with a negative voltage component. The slew rate
degrades as the output signal crosses through 0V (See Figures
5, 8, and 11), resulting in a slower overall negative slew rate.
Positive only signals have symmetrical slew rates as illustrated
in the large signal positive pulse response graphs (See Figures
4, 7, and 10).
R and C form a low pass network at the output, thus limiting
S
L
system bandwidth well below the amplifier bandwidth of
270MHz (for A = +1). By decreasing R as C increases (as
V
S
L
illustrated in the curves), the maximum bandwidth is obtained
without sacrificing stability. In spite of this, the bandwidth
decreases as the load capacitance increases. For example, at
A = +1, R = 62Ω, C = 40pF, the overall bandwidth is
V
S
L
limited to 180MHz, and bandwidth drops to 75MHz at A = +1,
V
R = 8Ω, C = 400pF.

PC Board Layout
This amplifier’s frequency response depends greatly on the
care taken in designing the PC board. The use of low
inductance components such as chip resistors and chip
capacitors is strongly recommended, while a solid
ground plane is a must!

Attention should be given to decoupling the power supplies.
A large value (10μF) tantalum in parallel with a small value
(0.1μF) chip capacitor works well in most cases.

Terminated microstrip signal lines are recommended at the
device’s input and output connections. Capacitance,
parasitic or planned, connected to the output must be
minimized, or isolated as discussed in the next section.
LOAD CAPACITANCE (pF)
FIGURE 1. RECOMMENDED SERIES OUTPUT RESISTOR vs
LOAD CAPACITANCE
Evaluation Board
Care must also be taken to minimize the capacitance to
ground at the amplifier’s inverting input (-IN), as this
capacitance causes gain peaking, pulse overshoot, and if
large enough, instability. To reduce this capacitance, the
designer should remove the ground plane under traces
connected to -IN, and keep connections to -IN as short as
possible.
The performance of the HFA1145 may be evaluated using
the HFA11XX Evaluation Board and a SOIC to DIP adaptor
like the Aries Electronics Part Number 14-350000-10. The
layout and schematic of the board are shown in Figure 2.
The V connection may be used to exercise the DISABLE
H
pin, but note that this connection has no 50Ω termination. To
order evaluation boards (part number HFA11XXEVAL),
please contact your local sales office.
An example of a good high frequency layout is the Evaluation
Board shown in Figure 2.
