ANALOG DEVICES 2 ADC 6 DAC 96 kHz 24-Bit AD1838A handbook
The AD1838A is a single-chip audio codec designed for applications such as DVD players, home theater systems, and automotive audio. It integrates three stereo digital-to-analog converters (DACs) and one stereo analog-to-digital converter (ADC), each featuring multibit sigma-delta modulators with Analog Devices' patented technology to reduce idle tones.
The device supports sample rates up to 96 kHz for all channels, with an additional 192 kHz rate available on the DAC. It includes flexible serial interfaces compatible with various DSP chips and AES/EBU receivers, operating from a single 5 V supply or separate digital supplies.
