INA332AIDGKRG4

Overview

The INA332AIDGKRG4 is a single-channel instrumentation amplifier manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical quiescent current of 415 µA. The device features a gain error of 0.4%, a common-mode rejection ratio (CMRR) of 60 dB, and a power supply rejection ratio (PSRR) of 86.02 dB. It supports a 3-dB bandwidth of 2 MHz and a slew rate of 5 V/µs, with input bias currents as low as 10 pA.

Feature Summary

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

Applications

• Battery-powered measurement systems
• Industrial process control sensors
• Medical instrumentation front-ends

Procurement Notes

Verify the complete part number including the RG4 suffix to ensure correct reel packaging and moisture sensitivity level. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for regional distribution restrictions or limited availability notices associated with this specific revision.

Selection Notes

Select this component when a single-supply operation between 2.5 V and 5.5 V is required alongside low power consumption. The VSSOP-8 package suits space-constrained designs. Ensure the 60 dB CMRR meets system noise requirements, as higher precision variants may be necessary for stringent common-mode rejection needs.

Part Context

This part belongs to the INA332 family of low-cost, low-power instrumentation amplifiers. The AIDGKT variant denotes the tube version, while the RG4 suffix indicates tape-and-reel packaging. It serves as a cost-effective solution for general-purpose analog signal amplification in portable and industrial devices.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the INA332AIDGKTG4. Verify that alternative packages match the physical footprint and thermal characteristics of the VSSOP-8 form factor.
