INA122PA

Overview

The INA122PA is a single-channel instrumentation amplifier from Texas Instruments, designed for low-power applications. It operates on a single supply voltage ranging from 2.2 V to 36 V. The device features a 120 kHz bandwidth and a slew rate of 160 mV/µs. Key electrical specifications include an input bias current of 25 nA, an input offset voltage of 500 µV, and a power supply current of 60 µA. It provides a common-mode rejection ratio (CMRR) of 83 dB. The component functions within a temperature range of -40°C to +85°C and is housed in an 8-pin PDIP package.

Feature Summary

Single-supply operation capability
Micro-power consumption design
High common-mode rejection ratio

Applications

Strain gauge measurements
Bridge sensor signal conditioning
Medical equipment front-ends

Procurement Notes

Verify the specific suffix 'PA' against official datasheets to confirm package type and temperature grade. Ensure compatibility with required PCB footprint dimensions for the 8-PDIP configuration. Cross-reference manufacturer part numbers to avoid confusion with surface-mount variants or different gain-setting options.

Selection Notes

Select this component when low quiescent current is critical alongside moderate bandwidth requirements. The high input impedance makes it suitable for interfacing with high-impedance sensors. Evaluate the trade-off between the fixed internal gain resistor and external gain adjustment needs compared to other instrumentation amplifiers in the series.

Part Context

Part of the INA1xx family of instrumentation amplifiers, the INA122 offers a balance of performance and power efficiency. It utilizes a three-op-amp architecture to achieve high input impedance and precise differential amplification. This series is widely recognized for its ease of use in precision analog signal processing tasks.
