The AD1835A is a high-performance single-chip CODEC featuring four stereo DACs and one stereo ADC.

Each DAC comprises a high-performance digital interpolation filter, a multi-bit sigma-delta 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 multi-bit sigma-delta modulators and decimation filters.

The AD1835A also contains an on-chip reference with a nominal value of 2.25 V.

The AD1835A contains a flexible serial interface that allows for glueless connection to a variety of DSP chips, AES/EBU receivers and sample rate converters. The AD1835A can be configured in Left-Justified, Right-Justified, I2S or DSP compatible serial modes. Control of the AD1835 is achieved by means of an SPI compatible serial port. While the AD1835A can be operated from a single 5 V supply, it also features a separate supply pin for its digital interface, which allows the device to be interfaced to other devices using 3.3 V power supplies.

The AD1835A is available in a 52 Lead MQFP package and is specified for the industrial temperature range of -40ºC to +85ºC.
