TPA1881Q-S5TR-S

Instrumentation, Op Amps, Buffer Amps Overview

The TPA1881Q-S5TR-S is a single-channel, zero-drift operational amplifier from the TPA188xQ series. It operates on a supply voltage of 4.5 V to 36 V or ±2.25 V to ±18 V. Key electrical parameters include a maximum offset voltage of ±50 μV and a gain-bandwidth product of 12 MHz. The device features a slew rate of 10 V/μs and input voltage noise density of 8 nV/√Hz at 1 kHz. Quiescent current is typically 2 mA per amplifier. It includes over-temperature protection that triggers at approximately 170°C. The component is housed in an SOT23-5 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'S5TR-S' corresponds to the SOT23-5 package and tape-and-reel quantity of 3000 units as listed in the manufacturer's order information table. Confirm the RoHS compatibility and halogen-free status required for your assembly process. Ensure the ESD handling procedures meet AEC-Q100 standards during installation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high DC accuracy is required alongside moderate bandwidth. The zero-drift technology eliminates the need for external trimming. Verify that the application load conditions allow for the specified rail-to-rail swing. Consider the 150 kHz chopping frequency when designing filters to avoid residual ripple interference.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TPA188xQ family of high-supply voltage amplifiers. The series includes dual-channel variants like the TPA1882Q. These devices utilize proprietary patented design techniques to achieve stable high-frequency response and low distortion while maintaining low quiescent current consumption across the operating temperature range.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the device handle over-temperature conditions?

The output enters a high impedance state when the die temperature reaches approximately 170°C. Functionality recovers when the temperature drops to around 150°C.

What is the recommended method to suppress residual ripple?

A post-filter should be placed at the output of the amplifier to suppress noise at the 150 kHz chopping frequency and its harmonics.
