The SSM2141 is an integrated differential amplifier intended to receive balanced line inputs in audio applications requiring a high level of noise immunity and optimum common-mode rejection. It achieves high common-mode rejection (100 dB) and low distortion performance (less than 0.002%), making it suitable for high-performance audio applications.
The SSM2141 differential line receiver provides high common‑mode rejection (100 dB typical) and low distortion (0.001 % THD) for audio applications. It features a fast slew rate of 9.5 V/µs and a small‑signal bandwidth of 3 MHz, making it suitable for line‑receiver, summing, and buffer amplifier designs.
The device is offered in two package options—8‑Pin Plastic DIP (P‑suffix) and Narrow Body SO (S‑suffix)—and includes detailed specifications, absolute maximum ratings, and typical performance curves. Proper decoupling and grounding are recommended to maintain its high CMR performance.
