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 means of an SPI compatible serial port. While the AD1838A can be operated from a single 5 V supply, it also features a separate supply pin for its digital interface that allows the device to be interfaced to other devices using 3.3 V power supplies. The AD1838A is available in a 52-lead MQFP package and is specified for the industrial temperature range of 40C to +85C.
