Many audio circuits including line receivers, microphone preamplifiers, and audio digital-to-analog converter output circuits desire very high common-mode rejection ratio. The INA1620 will help you achieve this common mode rejection ratio by combining on-chip precision matched thin-film resistors with a small size, low distortion audio operational amplifier. This video will go into more detail on how the INA1620 provides improved common mode rejection ratio in a typical audio circuit.
