GENERAL DESCRIPTION
●The SSM2166 integrates a complete and flexible solution for conditioning microphone inputs in 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.
●FEATURES
●Complete microphone conditioner in a 14-lead SOIC package
●Single 5 V operation
●Adjustable noise gate threshold
●Compression ratio set by external resistor
●Automatic limiting feature—prevents ADC overload
●Adjustable release time
●Low noise and distortion
●Power-down feature
●20 kHz bandwidth (±1 dB)
●APPLICATIONS
●Microphone preamplifiers/processors
●Computer sound cards
●Public address/paging systems
●Communication headsets
●Telephone conferencing
●Guitar sustain effects generators
●Computerized voice recognition
●Surveillance systems
●Karaoke and DJ mixers
