ANALOG MODE 6.4.1 Aux In and Ana In Description The AUX IN is an additional audio input to the ISD5100-Series, such as from the microphone circuit in a mobile phone “car kit.” This input has a nominal 694 mV p-p level at its minimum gain setting (0 dB). See the AUX IN Amplifier Gain Settings table on page 37. Additional gain is available in 3 dB steps (controlled by the I 2C serial interface) up to 9 dB. The ANA IN pin is the analog input from the telephone chip set. It can be switched (by the serial bus) to the speaker output, the array input or to various other paths. This pin is designed to accept a nominal 1.11 Vp-p when at its minimum gain (6 dB) setting. See the ANA IN Amplifier Gain Settings table on page 37. There is additional gain available in 3 dB steps controlled from the I 2C interface, if required, up to 15 dB.
