It features six audio playback channels each comprising a high-performance digital interpolation filter, a multibit sigma-delta 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, per channel, programmed through an SPI-compatible serial control port. The AD1833 is fully compatible with all known DVD formats, catering for up to 24-bit word lengths 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” standard 50 µs/15 µs digital de-emphasis filters at sample rates of 32 kHz, 44.1 kHz, and 48 kHz. The AD1833 has a very flexible serial data input port that allows for glueless interconnection to a variety of ADCs, DSP chips, AES/EBU receivers, and sample rate converters. The AD1833 can be configured in left-justified, I 2S, right-justified, or DSP serial port compatible modes. The AD1833 accepts serial audio data in MSB first, two’s complement format. While the AD1833 can be operated from a single 5 V power supply, it also features a separate supply pin for its digital interface which allows the device to be interfaced to devices using 3.3 V power supplies. It is fabricated on a single monolithic integrated circuit and is housed in a 48-lead LQFP package for operation over the tem- perature range –40 °C to +85°C. |
