INA149 - Difference amplifier for high common-mode voltage applications

The INA149 is the industry’s most accurate difference amplifier for high common-mode voltage applications up to +275 V. 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 degrees C. The amplifier also lowers initial gain error by 33 percent compared to the competition, while providing twice the slew rate to increase response time and overall system performance.
