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 AD1839 also contains an on-chip reference with a nominal value of 2.
25 V.
The AD1839 contains a flexible serial interface that allows for glueless connection to a variety of DSP chips, AES/EBU receivers, and sample rate converters.
The AD1839 can be configured in left-justified, right-justified, I2S, or DSP compatible serial modes.
Control of the AD1839 is achieved by means of an SP...
