Description and Introduction

High Common-Mode Rejection Differential Line Receiver applications requiring aREFERENCE 1 8 NChigh level of noise immunity and optimum common-modeSSM2141 7–IN 2 V+rejection. The SSM2141 typically achieves 100 dB of common-TOP VIEW 6+IN 3 OUTPUTmode rejection (CMR), whereas implementing an op amp with(Not to Scale)5V– 4 SENSE                  four off-the-shelf precision resistors will typically achieve  only40 dB of CMR—inadequate for high-performance audio.NC = NO CONNECTThe SSM2141 achieves low distortion performance bymaintaining a large slew rate of 9.5 V/μs and high open-loopgain. Distortion is less than 0.002% over the full audiobandwidth. The SSM2141 complements the SSM2142balanced line driver. Together, these devices comprise a fullyintegrated solution for equivalent transformer balancing ofaudio signals without the problems of distortion, EMI fields,and high cost.Additional

Application Scenarios & Design Considerations

High Common-Mode Rejection Differential Line Receiver

Alternative Part Number

  • THAT 1240P --: Pin-compatible high-performance balanced line receiver IC designed as a direct replacement for the SSM2141, with similar differential amplifier topology and excellent common-mode rejection.
  • INA134PA --: Balanced line receiver in a DIP-8 package with comparable function and performance to the SSM2141, suitable for audio differential input applications.
  • DRV134PA --: Audio balanced line driver/receiver family part in DIP-8 that can serve similar audio signal conditioning roles, though pinout and function should be verified against the SSM2141.
  • THAT 1240P08-U --: Pin-compatible high-performance differential line receiver with similar balanced input architecture, drop-in replacement for audio applications.
  • THAT1240P08-U --: Pin-compatible differential line receiver with similar balanced input architecture, often used as a direct substitute for the SSM2141 in audio applications.
