INA111AU Description

Short technical summary and product information.

The Texas Instruments INA111AU is a high-speed, FET-input instrumentation amplifier designed for demanding applications. It features a wide operating supply voltage range from 12V to 36V, making it versatile for various power configurations.

Key electrical specifications include a low input offset voltage of 500 µV maximum and a low input offset drift of 5 µV/°C maximum. The amplifier boasts a high common-mode rejection ratio (CMRR) of 106 dB minimum and a low input bias current of 0.02 nA maximum, facilitated by its FET input stage. The bandwidth at minimum gain is 2 MHz, and it offers a voltage gain range from 1 to 1000 V/V.

This instrumentation amplifier utilizes a current-feedback topology, enabling extended bandwidth and fast settling times. A single external resistor is sufficient to set any gain from 1 to over 1000. The INA111AU is available in PDIP (8-pin) and SOIC (16-pin) packages, suitable for different mounting requirements.

Applications for the INA111AU include medical instrumentation and data acquisition systems where high precision and speed are critical. Its robust design and performance characteristics make it a reliable choice for signal conditioning.
