CMX655D Description
Traditionally audio codecs have interfaced to electret microphones and speakers providing A-to-D and D-to-A functions using precision oversampling data converters. Recent advances in microphone design using MEMS techniques are now changing this, along with higher efficiency speaker drivers such as Class-D topologies. Both of these advances enable significant reductions in power consumption which is needed to address...
