SSM2167 Datasheet | Analog

FEATURES plete microphone conditioner in a 10-lead package Single 3 V operation Low shutdown current < 2 µA Adjustable noise gate threshold Adjustable pression ratio Automatic limiting feature prevents ADC overload Low noise and distortion: 0.2% THD + N 20 k Hz bandwidth APPLICATIONS Desktop, portable, or palmtop puters Telephone conferencing munication headsets Two-way munications Surveillance systems Karaoke and DJ mixers GENERAL DESCRIPTION The SSM2167 is a plete and flexible solution for conditioning microphone inputs in personal electronics and puter audio systems. It is also excellent for improving vocal clarity in munications 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 pression characteristic. The pression ratio is set by a single resistor...
