Quad channel microphone ADC with 2.5mW power consumption

Cirrus Logic has rolled out a quad channel microphone ADC that boasts a power consumption of less than 2.5mW per channel. The CS53L30 brings enhanced voice processing functions, such as noise suppression, acoustic echo cancellation, and multi-channel beamforming, to smart phones, tablets, and other consumer electronics. The converter also improves voice-capture processing for voice control and recognition.

Each of the CS53L30's four microphone channels has a dedicated mic bias for improved channel-to-channel separation, enhancing the performance of beamforming algorithms. Digital signal processing features, like high-pass filters, noise gates, and volume controls, provide further preconditioning.

The input front end of the CS53L30 accommodates a combination of digital and analogue microphone inputs in fully differential, pseudo-differential, and single-ended configurations. A single CS53L30 converter can output its four channels of audio data at a sample rate of up to 48kHz over two I2S ports or a single TDM port in master or slave mode. Up to four CS53L30 converters can be used together to output 16 channels of data over a single TDM line. The CS53L30 comes in 30-ball WLCSP and 32-pin QFN packages.

Datasheet for the CS53L30 ADC can be downloaded here.
