Product Overview

The SSM2167-1RMZ is a Low Voltage Microphone Preamplifier with variable compression and noise gating. This is a complete and flexible solution for conditioning microphone inputs in personal electronics and computer audio systems. It is also excellent for improving vocal clarity in communications and public address systems. A low noise voltage controlled amplifier (VCA) provides a gain that is dynamically adjusted by a control loop to maintain a set compression characteristic. The compression ratio is set by a single resistor and can be varied from 1:1 to over 10:1 relative to the fixed rotation point. Signals above the rotation point are limited to prevent overload and to eliminate popping. A downward expander (noise gate) prevents amplification of background noise or hum. This results in optimized signal levels prior to digitization, thereby eliminating the need for additional gain or attenuation in the digital domain.
  • Complete microphone conditioner
  • Single 3V operation
  • Low shutdown current (<2µA)
  • Adjustable noise gate threshold
  • Adjustable compression ratio
  • Automatic limiting feature prevents ADC overload
  • Low noise and distortion (0.2% THD + N)
  • 20kHz Bandwidth
ESD sensitive device, take proper precaution while handling the device.
