SSM2141PZ, Дифференциальный линейный приемник [DIP8]
The SSM2141PZ is an Integrated Differential Line Receiver intended to receive balanced line inputs in audio applications requiring a high level of noise immunity and optimum common-mode rejection. The SSM2141 typically achieves 100dB of common mode rejection (CMR), whereas implementing an op amp with four off-the-shelf precision resistors will typically achieve only 40dB of CMR-inadequate for high-performance audio. The SSM2141 achieves low distortion performance by maintaining a large slew rate of 9.5V/µs and high open-loop gain. Distortion is less than 0.002% over the full audio bandwidth. This device comprises a fully integrated solution for equivalent transformer balancing of audio signals without the problems of distortion and EMI fields. Additional applications for the SSM2141 include summing signals, differential preamplifiers and 600R low distortion buffer amplifiers.
