Overview
The AD1833AAST-REEL is a six-channel, 24-bit audio digital-to-analog converter (DAC) from Analog Devices. It supports sample rates of 96 kHz on all channels and 192 kHz on two channels. The device features multibit sigma-delta modulators with data-directed scrambling for improved linearity. Key specifications include a dynamic range of 110 dB and signal-to-noise ratio of 110 dB. It operates from a single 5 V analog supply and a separate 3.3 V to 5 V digital supply. The component is housed in a 48-lead LQFP package.
Feature Summary
- Six independent audio playback channels with integrated interpolation filters and multibit DACs
- Supports 16-, 20-, and 24-bit word lengths with flexible serial interface modes (I2S, Left/Right Justified, DSP)
- On-chip volume control with 1024 linear steps and software-controllable clickless mute per channel
- Digital de-emphasis processing compatible with Redbook standards at 32 kHz, 44.1 kHz, and 48 kHz
Applications
- DVD Video and Audio Players
- Home Theater Systems
- Automotive Audio Systems
- Set-Top Boxes
- Digital Audio Effects Processors
Procurement Notes
Verify the obsolete status of this component before procurement planning. Confirm that the REEL suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure compatibility with existing design infrastructure given the discontinued lifecycle stage.
Selection Notes
Select this part for applications requiring high-channel-count audio conversion with low jitter sensitivity. Verify that the system clock can provide the required internal MCLK frequencies (e.g., 24.576 MHz). Ensure the host processor supports the selected serial data format and SPI control port requirements.
Part Context
This component belongs to the AD1833A family of multichannel audio DACs. The A variant denotes industrial temperature range operation (-40°C to +85°C). The ST suffix identifies the 48-lead Low Profile Quad Flat Package. The REEL suffix specifies the bulk packaging format for manufacturing.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative solutions require evaluating current product lines from Analog Devices or other manufacturers with similar channel counts and performance metrics.
