INA101AM

Overview

The INA101AM is a very high accuracy instrumentation amplifier manufactured by Texas Instruments. It features a fixed gain of 1 V/V and supports a wide supply voltage range from 10 V to 40 V. Key electrical parameters include a maximum input offset voltage of 50 µV, a minimum common-mode rejection ratio (CMRR) of 106 dB, and a bandwidth of 25 kHz. The device operates with an input bias current of 30 nA and can deliver up to 10 mA output current per channel. It is housed in a CDIP-14 package and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides very high accuracy signal conditioning with low input offset voltage
• Delivers high common-mode rejection for precise differential measurements
• Supports wide dual-supply operation for flexible power integration

Applications

• Precision data acquisition systems
• Medical instrumentation
• Industrial process control sensors

Procurement Notes

Verify the specific suffix 'AM' against the official datasheet to confirm package type and temperature grade. Ensure compatibility with existing board layouts for the CDIP-14 footprint. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a fixed unity gain configuration is required alongside high precision. Consider the CDIP-14 through-hole package if prototyping or high-reliability mounting is needed. Evaluate the thermal performance at the upper temperature limit of 125°C.
