INA332AIDGKT

Overview

The INA332AIDGKT is a single-channel instrumentation amplifier from Texas Instruments, manufactured using CMOS technology. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical quiescent current of 415 µA. Key electrical specifications include a 2 MHz bandwidth, a slew rate of 5 V/µs, and a common-mode rejection ratio (CMRR) of 60 dB. The device features an input bias current of 10 pA and an input offset voltage of 8 mV. It is housed in an 8-pin VSSOP package and supports operation temperatures from -55°C to +125°C.

Feature Summary

• Low-power CMOS architecture designed for single-supply applications
• High input impedance suitable for precision signal conditioning
• Integrated gain setting via external resistor

Applications

• Signal conditioning for resistive bridge sensors
• Current sensing with high-side shunt configurations
• Data acquisition systems requiring low noise amplification

Procurement Notes

Verify the specific suffix 'G4' against the requested model number, as it indicates lead-free compliance and may affect ordering codes. Confirm the tape and reel quantity matches production requirements. Ensure the VSSOP-8 package dimensions align with PCB footprint designs. Check moisture sensitivity level handling procedures before assembly.

Selection Notes

Select this component when low power consumption is critical alongside moderate bandwidth requirements. The single-supply capability simplifies power design compared to dual-supply alternatives. Consider the 60 dB CMRR for applications with significant common-mode voltages. Evaluate the 8 mV offset voltage against system accuracy needs.

Part Context

This part belongs to the INA332 family of low-cost, low-power instrumentation amplifiers. It serves as a general-purpose solution for industrial and consumer electronics where space and power are constrained. The VSSOP-8 package allows for compact board layouts in portable devices.

Replacement Considerations

Check datasheets for pin-compatible alternatives within the same family, such as the INA332AIDGKR, noting differences in packaging format like cut tape versus reel.
