Ultra-low power voice codecs deliver ‘always on’ applications

CML MICROCIRCUITS CMX655D next generation voice codecs are aimed at existing telephony and emerging high quality speech applications in smart devices. Device brings greater integration at ultra-low power to enable advanced features in a wide range of applications. Device integrates two matched channels with Digital Signal Processing (DSP) along with a 1 Watt 90% efficient filterless Class D amplifier and support for digital MEMS microphones. Product requires very low power in all operating modes and is able to operate from a 1.8V to 3.6V supply, as opposed to requiring 5V to achieve a 1 Watt output power.
