ANA IN
The ANA IN pin is the analog input from the tele-
phone chip set. It can be switched (by the SPI bus)
to the speaker output, the array input or to various
other paths. This pin is designed to accept a nom-
inal 1.11 Vp-p when at its minimum gain (6 dB)
setting. There is additional gain available in 3 dB
steps controlled from the SPI bus, if required, up to
15 dB.
