AUX IN
The AUX IN is an additional audio input to the
ISD5008, such as from the microphone circuit in a
mobile phone “car kit.” This input has a nominal
700 mVp-p level at its minimum gain setting
(0 dB). See Table 5. Additional gain is available in
3 dB steps (controlled by the SPI bus) up to 9 dB.
