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 ISD5100-Series, such as from the microphone circuit in
a mobile phone âcar kit.â 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 I2C interface) up to
9 dB.
