INA101AG

Overview

The INA101AG is a very high accuracy instrumentation amplifier manufactured by Texas Instruments. It features a 14-pin CDIP package and operates within a supply voltage range of 10 V to 40 V. Key electrical specifications include a maximum input offset voltage of 50 µV, a minimum common-mode rejection ratio of 106 dB, and a gain bandwidth product of 300 kHz. The device supports gains from 1 V/V to 1000 V/V with a gain error of 0.002%. It draws 6.7 mA of operating current and functions across a temperature range of -55°C to +125°C.

Feature Summary

• Provides very high accuracy signal conditioning with minimal input offset voltage.
• Delivers exceptional common-mode rejection capabilities for precise differential measurements.
• Offers wide gain adjustment range from unity to 1000 times amplification.

Applications

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

Procurement Notes

Verify the specific manufacturer source, as the component was originally developed by Burr-Brown before its acquisition by Texas Instruments. Confirm that the 14-CDIP package matches your PCB footprint requirements. Ensure compliance with RoHS standards if required for your manufacturing process. Check for any obsolescence notices or end-of-life status updates from the supplier.

Selection Notes

Select this component when high precision and stability are critical for low-level signal amplification. The low input bias current and high CMRR make it suitable for sensor interfaces requiring minimal loading effects. Consider the through-hole mounting style and ceramic DIP package for applications demanding robust mechanical stability and thermal performance in harsh environments.

Part Context

The INA101AG belongs to the INA101 series of instrumentation amplifiers. This family is known for providing factory-trimmed accuracy without external components. The device integrates precision resistors on-chip to set the gain, simplifying circuit design while maintaining high performance characteristics typical of Burr-Brown heritage products now under the Texas Instruments portfolio.
