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 low distortion performance by maintaining a large slew rate and high open-loop gain.
The SSM2141 is an integrated differential amplifier designed to receive balanced line inputs in audio applications requiring high noise immunity and optimum common-mode rejection. It typically achieves 100 dB of common-mode rejection (CMR) and complements the SSM2142 balanced line driver to provide a fully integrated solution for equivalent transformer balancing without distortion or EMI issues.
The device features a wide bandwidth of 3 MHz, a slew rate of 9.5 V/us, and low distortion of 0.001% typical. It is available in 8-Pin Plastic DIP and 8-Pin Narrow Body SO packages with operating temperatures ranging from -40°C to +85°C.
