2.12.1.1 Common microphone inputs characteristics
The connection can be either differential or single-ended but
using a differential
connection in order to reject common mode noise and TDMA noise is strongly
recommended
. When using a single-ended connection, be sure to have a very
good ground plane, a very good filtering as well as shielding in order to avoid
any disturbance on the audio path.

The gain of MIC inputs is internally adjusted and can be tuned from 30dB to
51dB using an AT command.
