The ADAV803 is a stereo audio codec intended for applications The sample rate converter (SRC) provides high performance such as DVD or CD recorders that require high performance sample rate conversion to allow inputs and outputs that require and flexible, cost-effective playback and record functionality. different sample rates to be matched. The SRC input can be The ADAV803 features Analog Devices, Inc. proprietary, high selected from playback, auxiliary, DIR, or ADC (record). The performance converter cores to provide record (ADC), SRC output can be applied to the playback DAC, both main and playback (DAC), and format conversion (SRC) on a single chip. auxiliary record channels, and a DIT. Operation of the ADAV803 The ADAV803 record channel features variable input gain to is controlled via an I2C®-compatible serial interface, which allow for adjustment of recorded input levels and automatic allows the programming of individual control register settings. level control, followed by a high performance stereo ADC The ADAV803 operates from a single analog 3.3 V power whose digital output is sent to the record interface. The record supply and a digital power supply of 3.3 V with an optional channel also features level detectors that can be used in digital interface range of 3.0 V to 3.6 V. feedback loops to adjust input levels for optimum recording. The part is housed in a 64-lead LQFP package and is character- The playback channel features a high performance stereo DAC ized for operation over the commercial temperature range of with independent digital volume control. −40°C to +85°C.
