C In is the compressor input. This pin is internally
biased and has an input impedance of 12.5 kΩ.
C In must be ac–coupled.
Supply input for the audio section, filters, A/D
Converters, and Data Slicer. Allowable range is 2.7
to 5.5 V. Good bypassing is required.
Output of the Microphone amplifier. Maximum
output swing is 3.0 V pp for V CC
Maximum output current is >1.0 mA peak.
Inverting input of the microphone amplifier. Gain
and frequency response are set with external
resistors and capacitors from this pin to the audio
source and to MCO.
Analog ground for the audio section filters. VAG is
equal to VB and is buffered from VB. Maximum
current which can be sourced from this pin is
500 µA.
An internal 1.5 V reference for several sections.
This voltage is adjustable with bits 3/20–17.
Maximum source current is 100 µA. PSRR, noise
and crosstalk depends on the external capacitor.
Supply pin for the power amplifier outputs.
Allowable range is 2.7 to 5.5 V. Good bypassing is
required.
