CMX655D Ultra-Low Power Voice Codec

CML Micro CMX655D Ultra-Low Power Voice Codec features an integrated digital microphone interface that connects single or dual MEMS microphones to the device, with parallel processing of each data stream to maintain phase alignment between the two channels. In the reverse channel, digital voice data drives a Class D speaker driver, also featuring programmable filtering and digital gain control. This architecture operates with much higher efficiency than conventional speaker drivers. An additional low-level output is also provided. The CMX655D is available in a small VQFN-24 package, ideal for space-constrained applications.
