Amplifiers for voltage applications

In December 2011, Texas Instruments introduced accurate difference amplifiers for high common mode voltage applications up to +275 V.

Features and USP: With a best-in-class common mode rejection ratio (CMRR) of 100 dB, the INA149 increases overall measurement accuracy by 2x compared to the competition, and is the first high voltage difference amplifier with a specified minimum 90-dB CMRR performance in harsh, high temperature environments up to 125° C. The amplifier also lowers initial gain error by 33 per cent compared to the competition, while providing twice the slew rate to increase response times and overall systems performance.
