APPLICATIONS DVD Video and Audio Players Home Theater Systems Automotive Audio Systems Audio/Visual Receivers Digital Audio Effects Processors GENERAL DESCRIPTION
The AD1838A is a high performance single-chip codec featuring three stereo DACs and one stereo ADC.
Each DAC comprises a high performance digital interpolation filter, a multibit ⌺-⌬ modulator featuring Analog Devices’ patented technology, and a continuous-time voltage out analog section.
Each DAC has independent volume control and clickless mute functions.
The ADC comprises two 24-bit conversion channels with multibit ⌺-⌬ modulators and decimation filters.
The AD1838A also contains an on-chip reference with a nominal value of 2.
25 V.
The AD1838A contains a flexible serial interface that allows glueless connection to a variety of DSP chips, AES/EBU receivers, and sample rate converters.
The AD1838A can be configured in left-justified, right-justified, I2S, or DSP compatible serial modes.
Control of the AD1838A is achieved by m...
