TPA1881/TPA1882
40-V, 12-MHz, Zero-Drift Op Amps
Features
Description
Supply Voltage: 4.5 V to 40 V
or ±2.25 V to ±20 V
The TPA188X series amplifiers are the newest high
supply voltage amplifiers with 15 μV low offset, low
noise, and stable high-frequency response. They
incorporate 3PEAK’s proprietary and patented design
techniques to achieve excellent AC performance with
12 MHz bandwidth, 12 V/μs slew rate, and low
distortion while drawing only 2000 μA of quiescent
current per amplifier. The input common-mode
voltage range extends to V–, and the outputs swing
rail-to-rail.
Offset Voltage: ±15 μV Maximum
Differential Input Voltage Range to Supply Rail,
can Work as Comparator
Input Rail to –VS, Rail to Rail Output
Bandwidth: 12 MHz
Slew Rate: 12 V/μs
Over-Temperature Protection
Low Noise: 6 nV/√Hz at 1 kHz
2 kV HBM, 1 kV CDM
–40°C to 125°C Operation Temperature Range
Applications
Instrumentation
Active Filters, ASIC Input or Output Amplifier
The TPA188X has an over-temperature protection
feature to guarantee chip safety. The output of
TPA188X will enter high impendence when the die
temperature reaches around 170°C and will recover
the function when the die temperature is down to
around 150°C. The product has a very small power
temperature coefficient, which is helpful for
temperature-sensitive applications.

(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.
(2) The inputs are protected by ESD protection diodes to the negative power supply. If the input extends more than 300 mV
beyond the negative power supply, the input current should be limited to less than 10 mA.
(3) 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.

40-V, 12-MHz, Zero-Drift Op Amps
Detailed Description
Overview
The TPA188x series op amps can operate on a single-supply voltage (4.5 V to 40 V), or a split-supply voltage
(±2.25 V to ±20 V), making them highly versatile and easy to use. The power-supply pins should have local
bypass ceramic capacitors (typically 0.01 μF to 0.1 μF). Parameters that can exhibit variance with regard to
operating voltage or temperature are presented in the Typical Characteristics.

Application and Implementation
NOTE
Information in the following application sections is not part of the 3PEAK’s component specification and
3PEAK does not warrant its accuracy or completeness. 3PEAK’s customers are responsible for determining
suitability of components for their purposes. Customers should validate and test their design implementation
to confirm system functionality.
Low Side Current Sensing Application
Figure 20 shows the TPA188X configured in a low-side current sensing application. The low-side current sensing
method consists of placing a sense resistor between the load and the circuit ground. The voltage dropping
across the resistor is amplified by different amplifier circuits with TPA188X. The VREF can be used to add bias
voltage to output voltage. Particular attention must be paid to the matching and precision of R1, R2, R3, and
R4, to maximize the accuracy of the measurement.
Figure 20. Dual Supply Operation Connections
Power Supply Recommendations
Place 0.1-μF bypass capacitors close to the power supply pins for reducing coupling errors from the noisy or
high impedance power supplies.
