Revision A1
MICROPHONE INPUTs
The microphone inputs transfer the voice signal to the on-chip AGC preamplifier, or directly to the
CODEC INPUT MUX, depending on the selected path. The AGC circuit has a range of 45 dB in order
to deliver a nominal 694 mV p-p into the storage array from a typical electret microphone output of 2 to
20 mV p-p. The input impedance is typically 10k
.
The MICBS pin provides a 2.2V bias voltage for the external microphone only when the AGC is
powered up. Using this regulated bias voltage results in less supply noise coupling into the MIC+ and
MIC- pins compared to the situation in which the external microphone is powered up through the power
supply. It also saves current during power down.
The ACAP pin provides the capacitor connection for setting the parameters of the microphone AGC
circuit. It should have a 4.7 μF capacitor connected to ground. It cannot be left floating. This is because
the capacitor is also used in the playback mode for the AutoMute circuit or when signal compression is
chosen (AMT0 set). The AutoMute circuit reduces the amount of noise present in the output during
quiet pauses. Tying the ACAP pin to ground gives maximum gain. Tying it to VCCA gives minimum
gain for the AGC amplifier, but cancels the AutoMute function.
