Low-Power, Stereo Audio Codec
with FlexSound Technology
Route microphone signals from the microphone to the ICs
as a differential pair, ensuring that the positive and nega-
tive signals follow the same path as closely as possible
with equal trace length. When using single-ended micro-
phones or other single-ended audio sources, ground the
negative microphone input as close as possible to the
audio source and then treat the positive and negative
traces as differential pairs.
An evaluation kit (EV kit) is available to provide an exam-
ple layout for the IC. The EV kit allows quick setup of the
IC and includes easy-to-use software allowing all internal
registers to be controlled.
