ADAV801 General Description
The ADAV801 is a stereo audio codec intended for applications such as DVD or CD recorders that require high performance and flexible, cost-effective playback and record functionality. The ADAV801 features Analog Devices' proprietary, high performance converter cores to provide record (ADC), playback
(DAC), and format conversion (SRC) on a single chip. The ADAV801 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 that 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 that require 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. Operation of the ADAV801 is controlled via an SPI-compatible serial interface, which allows the programming of individual control register settings. The ADAV801 operates from a single analog 3.3 V power supply and a digital power supply of 3.3 V with optional digital interface range of 3.0 V to 3.6 V.
