INA122P

Overview

The INA122P is a single-supply, micro-power instrumentation amplifier manufactured by Texas Instruments. It features a wide supply voltage range from 2.2 V to 36 V and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a 3dB bandwidth of 120 kHz, a slew rate of 160 mV/µs, and a typical common-mode rejection ratio (CMRR) of 83 dB. The device draws a maximum operating supply current of 60 µA, with an input bias current of 25 nA and an input offset voltage of 500 µV. It is housed in an 8-pin PDIP package.

Feature Summary

Micro-power consumption suitable for battery-operated applications
Wide single-supply voltage operation capability
High common-mode rejection ratio for precision signal conditioning

Applications

Battery-powered sensor interfaces
Strain gauge and bridge circuits
Medical instrumentation

Procurement Notes

Verify the specific suffix 'P' indicates the 8-pin PDIP package configuration when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides official datasheets matching the INA122 series specifications. Check for any updated revision notes that may affect pinout or electrical characteristics compared to legacy Burr-Brown versions.

Selection Notes

Select this component for applications requiring low power consumption alongside moderate precision. The wide supply voltage range allows flexibility in system design without needing dual supplies. Consider the 120 kHz bandwidth limit for high-speed signal processing needs. Evaluate the 500 µV input offset voltage against required measurement accuracy thresholds.

Part Context

The INA122 belongs to the INA122 family of instrumentation amplifiers originally developed by Burr-Brown and now produced by Texas Instruments. This series is designed for general-purpose precision applications where low power and wide supply voltage ranges are critical. It serves as a cost-effective solution for interfacing low-level signals from sensors.
