It features six audio playback channels, each comprising a high performance digital interpolation filter, a multibit S-D modulator featuring Analog Devices’ patented technology, and a continuous-time voltage-out analog DAC section. Other features include an on-chip clickless attenuator and mute capability for each channel, programmed through an SPI compatible serial control port. The AD1833A is fully compatible with all known DVD formats, accommodating word lengths of up to 24 bits at sample rates of 48 kHz and 96 kHz on all six channels while supporting a 192 kHz sample rate on two channels. It also provides the Redbook stan- dard 50 ms/15 ms digital de-emphasis filters at sample rates of 32 kHz, 44.1 kHz, and 48 kHz. The AD1833A has a very flexible serial data input port that allows glueless interconnection to a variety of ADCs, DSP chips, AES/EBU receivers, and sample rate converters. It can be con- figured in right-justified, left-justified, I 2S, or DSP serial port compatible modes. The AD1833A accepts serial audio data in MSB first, twos complement format. The AD1833A can be operated from a single 5 V power supply; it also features a separate supply pin for its digital interface that allows it to be interfaced to devices using 3.3 V power supplies. The AD1833A is fabricated on a single monolithic integrated circuit and is housed in a 48-lead LQFP package for operation from –40 ∞C to +85∞C. |
