INA4180A1IPWR

Instrumentation, Op Amps, Buffer Amps Overview

The INA4180A1IPWR is a quad-channel current sense amplifier manufactured by Texas Instruments. It features a fixed gain of 20 V/V and operates within a supply voltage range of 2.7 V to 5.5 V. The device supports a common-mode voltage up to 26 V and offers a bandwidth of 350 kHz. Key electrical specifications include an input offset voltage of 100 µV, a common-mode rejection ratio of 100 dB, and a maximum gain error of 0.1%. It draws 900 µA of operating current and is housed in a TSSOP-14 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IPWR corresponds to the TSSOP-14 package and tape-and-reel delivery format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly line. Ensure the 26 V common-mode rating aligns with your circuit's maximum voltage stress conditions before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple isolated current measurements are required on a single board. The quad configuration reduces footprint compared to discrete amplifiers. Verify that the 20 V/V gain provides sufficient output swing for your ADC input range without saturation at maximum expected load currents.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA4180 family of quad-channel current sense amplifiers. It complements other variants like the INA4181 which offers bidirectional sensing capabilities. The series is designed for applications requiring compact solutions for monitoring multiple power rails simultaneously in industrial and computing environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check datasheet compatibility for pinout and electrical parameters when substituting with other INA4180 variants or similar quad-channel amplifiers from different manufacturers.
