Overview
The AD1833CST-REEL is a multichannel, 24-bit, 192 kHz digital-to-analog converter (DAC) from Analog Devices. It integrates six audio playback channels, each featuring a digital interpolation filter and a multibit sigma-delta modulator. The device supports sample rates of 96 kHz on all six channels and 192 kHz on two channels. Key specifications include a dynamic range of 107 dB and an SNR of 110 dB. It operates from a single 5 V analog supply and a separate 3.3 V to 5 V digital interface supply, housed in a 48-lead LQFP package.
Feature Summary
- Six-channel architecture with independent volume control and clickless mute per channel
- Multibit sigma-delta modulators with data-directed scrambling for reduced idle tones
- Flexible serial data port supporting I2S, left/right justified, DSP, packed, and TDM modes
- On-chip digital de-emphasis filters for 32 kHz, 44.1 kHz, and 48 kHz sample rates
Applications
- DVD Video and Audio Players
- Home Theater Systems
- Automotive Audio Systems
- Set-Top Boxes
- Digital Audio Effects Processors
Procurement Notes
Verify the 'C' suffix indicates industrial temperature grade (-40°C to +85°C). Confirm the '-REEL' suffix denotes tape-and-reel packaging. Check current availability status as this component may be discontinued or subject to long lead times. Ensure ESD precautions are observed during handling due to sensitivity.
Selection Notes
Select this model for applications requiring six discrete audio outputs with high resolution. Verify compatibility with the host processor's serial interface mode (I2S, DSP, etc.). Ensure the system clock allows for the required internal MCLK of 24.576 MHz for 48/96 kHz operation or appropriate scaling for 192 kHz. Confirm power supply constraints match the 5 V analog and 3.3 V/5 V digital requirements.
Part Context
This part belongs to the AD1833 family of high-performance audio DACs. The 'C' variant specifies the industrial temperature range, distinguishing it from the 'A' variant which may have different performance thresholds or temperature ratings. The 'ST' package code refers to the Low Profile Quad Flat Package. The 'REEL' designation indicates bulk tape packaging for automated assembly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives only if they support identical 6-channel architectures and similar electrical specifications.
