AUX OUT (Auxiliary Output)
The AUX OUT is an additional audio output pin to be used, for example, to drive the speaker circuit in a
“car kit.” It drives a minimum load of 5 k
and up to a maximum of 1 V p-p. The AC signal is
superimposed on approximately 1.2 VDC bias and must be capacitively coupled to the load.

ANA IN (Analog Input)
The ANA IN pin is the analog input from the telephone chip set. It can be switched (by the I
2
C 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
I
2
C interface.
