Stereo Codec with Differential DAC Outputs, SPDIF and SPI Interface

The ADAV802 is a stereo audio codec intended for applications, such as DVD or CD recorders, requiring high performance, flexible and cost effective playback and record functionality. The ADAV802 features Analog Devices proprietary, high performance converter cores to provide record (ADC), playback (DAC) and format conversion (SRC) in a single chip. The ADAV802 record channel features variable input gain to allow for adjustment of recorded input levels and Automatic Level Control, followed by a high performance stereo ADC whose digital output is sent to the record interface. The record channel also features Level Detectors which can be used in feedback loops to adjust input levels for optimum recording. The playback channel features a high performance stereo DAC with independent digital volume control.
