INA2332AIPWR

Overview

The INA2332AIPWR is a dual-channel instrumentation amplifier from Texas Instruments, housed in a TSSOP-14 package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical quiescent current of 415 uA per channel. The device features a 2 MHz bandwidth and a slew rate of 5 V/us. Key electrical specifications include a common-mode rejection ratio (CMRR) of 60 dB, an input bias current of 10 pA, and an input offset voltage of 8 mV. Gain error is specified at 0.4%, while the power supply rejection ratio (PSRR) reaches 86.02 dB. It supports an operating temperature range from -55°C to +125°C.

Feature Summary

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and functional compatibility. Ensure environmental compliance requirements match project standards. Confirm thermal management needs for the TSSOP-14 package under maximum load conditions. Validate that the single-supply capability aligns with system power rails.

Selection Notes

Select this component when dual-channel amplification with low power consumption is required. The 2 MHz bandwidth suits moderate-speed applications. Consider the 60 dB CMRR for noise-sensitive environments. Verify that the 2.5 V to 5.5 V supply range fits the design constraints. Check if the TSSOP-14 footprint meets PCB layout limitations.
