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
AUX IN Amplifier Gain Settings table on page 26. Additional gain is available in 3 dB steps (controlled
by the I²C interface) up to 9 dB.
