Cx31993 | Datasheet _hot_

As a High Definition (HD) Audio codec, the Cx31993 is responsible for converting analog audio signals (like sound from a microphone) into digital data that a computer can process, and conversely, converting digital audio files back into analog signals that can be played through speakers or headphones. Its popularity stems from its small footprint, energy efficiency, and robust processing power, making it a staple in modern mobile computing architectures.

Section 7.2 of the datasheet details the mono ADC with 93dB DNR. It supports analog microphones with a bias voltage of 2.2V. No digital mic (PDM) support. Cx31993 Datasheet
