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.
ANA IN Input Modes
ANA IN Amplifier Gain Settings
1. Gain from ANA IN to SP+/-
2. Gain from ANA IN to ARRAY IN
3. 0TLP Input is the reference Transmission Level Point that is used for testing.
This level is typically 3 dB below clipping
4. Speaker Out gain set to 1.6 (High). (Differential)

AUX IN (Auxiliary Input)
The AUX IN is an additional audio input to the ISD5116, 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 following table.
Additional gain is available in 3 dB steps (controlled by the I
2
C interface) up to 9 dB.
