Overview
The AD1833ACST-REEL is a multichannel, 24-bit, 192 kHz digital-to-analog converter (DAC) from Analog Devices. It integrates six audio playback channels, each with a digital interpolation filter and sigma-delta modulator. The device supports 5 V stereo audio systems with 3.3 V tolerant digital interfaces. Key electrical parameters include a dynamic range of 110 dB, -95 dB THD+N in two-channel mode, and -94 dB THD+N in six-channel mode. It operates on a single 5 V supply for analog and core logic, with a separate 3.3 V to 5 V supply for the digital interface. The component is housed in a 48-lead LQFP package.
Feature Summary
- Six-channel architecture supporting up to 24-bit word lengths at sample rates of 48 kHz, 96 kHz, or 192 kHz on two channels.
- Multibit sigma-delta modulators with data-directed scrambling for perfect differential linearity and reduced idle tones.
- On-chip volume control with 1024-step linear scale and software-controllable clickless mute per channel.
- Flexible serial data port compatible with I2S, left-justified, right-justified, DSP modes, packed data, and TDM.
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. Confirm that the ST-48 package option matches the target PCB footprint. Ensure the design accommodates the specific power supply requirements: 5 V for AVDD/DVDD1 and 3.3 V to 5 V for DVDD2. Check for ESD sensitivity during handling and storage.
Selection Notes
Select this model for applications requiring high channel count (six channels) with high fidelity (110 dB dynamic range). Choose the AC version for industrial temperature ranges (-40°C to +85°C). Consider the 48-lead LQFP package constraints. Verify compatibility with the host processor's serial interface modes (I2S, DSP, etc.) and clocking requirements (MCLK selection options).
Part Context
The AD1833ACST-REEL is part of the AD1833A family of multichannel DACs. The 'C' suffix denotes the industrial temperature range (-40°C to +85°C), while 'ST' indicates the Low Profile Quad Flat Package (LQFP). The '-REEL' suffix specifies the tape and reel packaging format. This component is designed for high-performance digital audio playback systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, alternative solutions may require redesigning the audio interface and power supply rails to match new components.
