The ADAV801 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 ADAV801 features Analog Devices, Inc. proprietary, high selected from playback, auxiliary, DIR, or ADC (record). The performance converter cores to provide record (ADC), playback SRC output can be applied to the playback DAC, both main and (DAC), and format conversion (SRC) on a single chip. The auxiliary record channels, and a DIT. ADAV801 record channel features variable input gain to allow Operation of the ADAV801 is controlled via an SPI-compatible for adjustment of recorded input levels and automatic level serial interface, which allows the programming of individual control, followed by a high performance stereo ADC whose control register settings. The ADAV801 operates from a single digital output is sent to the record interface. The record channel analog 3.3 V power supply and a digital power supply of 3.3 V also features level detectors that can be used in feedback loops with an optional digital interface range of 3.0 V to 3.6 V. to adjust input levels for optimum recording. The playback channel features a high performance stereo DAC with The part is housed in a 64-lead LQFP package and is character- independent digital volume control. ized for operation over the commercial temperature range of −40°C to +85°C.
