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. The Sample Rate Converter (SRC) provides high performance sample-rate conversion to allow inputs and outputs requiring different sample rates to be matched. The SRC input can be selected from Playback, Auxiliary, DIR or ADC (record). The SRC output can be applied to the Playback DAC, both main and Auxiliary record channels and a DIT.
