ANA IN (Analog Input)
The ANA IN pin is the analog input from the telephone chip set. It can be switched (by the I2C
interface) to the speaker output, the array input or to various other paths. This pin is designed to
accept a nominal 1.11 V p-p when at its minimum gain (6 dB) setting. There is additional gain
available, if required, in 3 dB steps, up to 15 dB. The gain settings are controlled from the I2C
interface.
