TP1251/TP1252 /TP1254
36V Single Supply, Low Power, Precision Op‐amps
Description
Features
The TP1251/TP1252/TP1254 are low power precision
EMI Hardened 36V CMOS op-amps featuring EMIRR
of 108dB at 1000MHz. These devices provide very low
quiescent current which are very suitable for low power
or battery power supply system. The rail-to-rail output
swing and input range that includes V– makes the
TP125x ideal choices for interfacing to modern,
single-supply and precision data converters.
Low Offset Voltage: 250 μV Maximum
Low Current Consumption:75 μA
High EMIRR: 108dB at 1000MHz
Low Noise: 50 nV/√Hz(f= 1kHz)
Wide Supply Range: 2.7V to 36V
High Bandwidth: 1.3 MHz
Low Input Bias Current: 3 pA Typical
Below-Ground (V-) Input Capability to -0.3V
Rail-to-Rail Output Voltage Range
High Output Current: 30 mA
The TP125x op-amps offer lower noise, offset voltage,
offset drift over temperature and bias current. In
addition, the devices have better common-mode
rejection and slew rates.
Unit Gain Stable
–40°C to 125°C Operation Range
Robust 3kV – HBM and 2kV – CDM ESD Rating
The TP125x family, exhibiting high input impedance
and low noise, is excellent for small signal conditioning
for high impedance sources, such as piezoelectric
transducers. Because of the micro power dissipation
levels, the devices work well in hand held monitoring
and remote sensing applications.
Applications
The TP1251 is single channel version available in 8-pin
SOIC and 5-pin SOT23 packages. The TP1252 is dual
channel version available in 8-pin SOIC and MSOP
packages. The TP1254 is quad channel version
available in 14-pin SOIC and TSSOP packages.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input
current should be limited to less than 10mA.
Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.

TP1251/TP1252TP1254
36V Single Supply, Lower Power, Precision Op‐amps
Pin Functions
-IN: Inverting Input of the Amplifier. Voltage range of this
–
V– or VS: Negative Power Supply. It is normally tied to
ground. It can also be tied to a voltage other than
ground as long as the voltage between V+ and V– is from
2.7V to 36V. If it is not connected to ground, bypass it
with a capacitor of 0.1μF as close to the part as
possible.
pin can go from V– to (V+ - 2.0V).
+IN: Non-Inverting Input of Amplifier. This pin has the
same voltage range as –IN.
V+ or +VS: Positive Power Supply. Typically the voltage
is from 2.7V to 36V. Split supplies are possible as long
as the voltage between V+ and V– is between 2.7V and
36V. A bypass capacitor of 0.1μF as close to the part as
possible should be used between power supply pins or
between supply pins and ground.
OUT: Amplifier Output. The voltage range extends to
within milli-volts of each supply rail.
N/C: No connection.
Operation
The TP125x op-amps have input signal range from V– to (V+ – 2.0V). The output can extend all the way to the supply
rails. The input stage is comprised of a PMOS differential amplifier. The Class-AB control buffer and output bias stage
uses a proprietary compensation technique to take full advantage of the process technology to drive very high
capacitive loads. This is evident from the transient over shoot measurement plots in the Typical Performance
Characteristics.
Applications Information
EMI Harden
The EMI hardening makes the TP1251/1252/1254 a must for almost all op amp applications. Most applications are
exposed to Radio Frequency (RF) signals such as the signals transmitted by mobile phones or wireless computer
peripherals. The TP1251/1252/1254 will effectively reduce disturbances caused by RF signals to a level that will be
hardly noticeable. This again reduces the need for additional filtering and shielding Using this EMI resistant series of
op amps will thus reduce the number of components and space needed for applications that are affected by EMI, and
will help applications, not yet identified as possible EMI sensitive, to be more robust for EMI.
Wide Supply Voltage
The TP1251/1252/1254 operational amplifiers can operate with power supply voltages from 2.7V to 36V. Each
amplifier draws 0.8mA quiescent current at 36V supply voltage. The TP1251/1252/1254 is optimized for wide
bandwidth low power applications. They have an industry leading high GBW to power ratio and the GBW remains
nearly constant over specified temperature range.
Low Input Bias Current
The TP1251/1252/1254 is a CMOS OPA family and features very low input bias current in pA range. The low input
bias current allows the amplifiers to be used in applications with high resistance sources. Care must be taken to
minimize PCB Surface Leakage. See below section on “PCB Surface Leakage” for more details.
PCB Surface Leakage
In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be
considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity
conditions, a typical resistance between nearby traces is 1012Ω. A 5V difference would cause 5pA of current to flow,
which is greater than the TP1251/1252/1254 OPA’s input bias current at +27°C (±3pA, typical). It is recommended to
use multi-layer PCB layout and route the OPA’s -IN and +IN signal under the PCB surface.

TP1251 / TP1252TP1254
36V Single Supply, Low Power, Precision Op‐amps
The effective way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is
biased at the same voltage as the sensitive pin. An example of this type of layout is shown in Figure 1 for Inverting
Gain application.
1. For Non-Inverting Gain and Unity-Gain Buffer:
a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface.
b) Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the Common Mode input voltage.
2. For Inverting Gain and Trans-impedance Gain Amplifiers (convert current to voltage, such as photo detectors):
a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the
op-amp (e.g., VDD/2 or ground).
b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface.
Figure 1 The Layout of Guard Ring
Ground Sensing and Rail to Rail Output
The TP1251/1252/1254 family has excellent output drive capability. It drives 2k load directly with good THD
performance. The output stage is a rail-to-rail topology that is capable of swinging to within 50mV of either rail.
The maximum output current is a function of total supply voltage. As the supply voltage to the amplifier increases, the
output current capability also increases. Attention must be paid to keep the junction temperature of the IC below 150°C
when the output is in continuous short-circuit. The output of the amplifier has reverse-biased ESD diodes connected to
each supply. The output should not be forced more than 0.3V beyond either supply, otherwise current will flow through
these diodes.
Power Supply Layout and Bypass
The TP1251/1252/1254 OPA’s power supply pin (VDD for single-supply) should have a local bypass capacitor (i.e.,
0.01μF to 0.1μF) within 2mm for good high frequency performance. It can also use a bulk capacitor (i.e., 1μF or larger)
within 100mm to provide large, slow currents. This bulk capacitor can be shared with other analog parts.
Ground layout improves performance by decreasing the amount of stray capacitance and noise at the OPA’s inputs
and outputs. To decrease stray capacitance, minimize PC board lengths and resistor leads, and place external
components as close to the op amps’ pins as possible.
Proper Board Layout
To ensure optimum performance at the PCB level, care must be taken in the design of the board layout. To avoid
leakage currents, the surface of the board should be kept clean and free of moisture. Coating the surface creates a
barrier to moisture accumulation and helps reduce parasitic resistance on the board.
Keeping supply traces short and properly bypassing the power supplies minimizes power supply disturbances due to
output current variation, such as when driving an ac signal into a heavy load. Bypass capacitors should be connected
as closely as possible to the device supply pins. Stray capacitances are a concern at the outputs and the inputs of the
amplifier. It is recommended that signal traces be kept at least 5mm from supply lines to minimize coupling.
A variation in temperature across the PCB can cause a mismatch in the Seebeck voltages at solder joints and other
points where dissimilar metals are in contact, resulting in thermal voltage errors. To minimize these thermocouple
effects, orient resistors so heat sources warm both ends equally. Input signal paths should contain matching numbers
and types of components, where possible to match the number and type of thermocouple junctions. For example,
dummy components such as zero value resistors can be used to match real resistors in the opposite input path.
Matching components should be located in close proximity and should be oriented in the same manner. Ensure leads
are of equal length so that thermal conduction is in equilibrium. Keep heat sources on the PCB as far away from
amplifier input circuitry as is practical.
