CMX655D Datasheet (CML) - Ultra Low Power Voice Codec

CMX655D, Ultra Low Power Voice Codec

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
