The SSM2143 is a differential line receiver with high common-mode rejection, ultra-low distortion, high gain, fast slew rate and wide bandwidth.
The SSM2143 is an integrated differential amplifier intended for balanced line inputs in audio applications that require high immunity to common‑mode noise. It offers a typical 90 dB common‑mode rejection, 0.0006 % THD+N at 1 kHz, and a fast slew rate of 10 V/µs. Two gain settings are available (G = 1/2 or 2) and the device can handle input signals up to +28 dBu.
The datasheet provides full electrical specifications, pin‑out information for Mini‑DIP and SOIC packages, absolute maximum ratings, and application examples showing how the SSM2143 pairs with the SSM2142 line driver to form a balanced audio transmission system.
