General purpose audio codec featuring 2 analog-to-digital converters (ADCs) and 2 digital-to-analog converters (DACs), each with 24-bit resolution. Supports sampling rates up to 96 ksps and offers a signal-to-noise ratio of 105 dB with THD+N of -90 dB. Operates with analog power supplies ranging from 1.8V to 3.65V, with typical voltages at 2.5V or 3.3V. Interface options include serial I2C, I2S, and SPI. Packaged in a 32-pin LFCSP EP (Lead Frame Chip Scale Package) with an exposed pad, measuring 5x5x0.83mm, suitable for surface mounting.
