3.10 Microphone
The microphone is placed to the front cover and contacted to main PCB. The audio signal is passed to
AIN1P and AININ pins of AD6535. The voltage supply VMIC is output from AD6535, and is a biased
voltage for the AIN1P. The AIN1P and AIN1N signals are then A/D converted by the voiceband ADC
part of AD6535.The digitized speech (PCM 8KHz ,16KHz) is then passed to the DSP section of
AD6527B for processing (coding, interleaving etc).
