AD1833AST-REEL

Overview

The AD1833AST-REEL is a six-channel audio digital-to-analog converter (DAC) from Analog Devices, operating at sampling rates up to 192 kHz with 24-bit resolution. It features a serial interface and delivers a signal-to-noise ratio of 120 dB within a dynamic range of 107 dB. The device functions on a single 5 V supply, drawing 90 mA, and operates between -40°C and +85°C. Packaged in an LQFP-48 format, it provides six analog outputs with a gain error of +/- 3% FSR.

Feature Summary

• Six independent DAC channels supporting high-fidelity multi-channel audio applications
• 24-bit resolution with 192 kHz maximum sampling rate for precise audio reproduction
• Integrated 120 dB SNR and 107 dB dynamic range performance
• Serial digital interface compatible with standard DSP and microcontroller systems

Applications

• Professional audio mixing consoles and recording equipment
• High-end home theater and surround sound processing units
• Digital audio workstations and broadcast infrastructure

Procurement Notes

Verify the specific suffix 'REEL' against official documentation to confirm packaging type and moisture sensitivity handling requirements. Confirm current lifecycle status as distribution data indicates potential end-of-life conditions for this component series.

Selection Notes

Select this component when designing multi-channel audio systems requiring high resolution and low noise. Ensure the design supports a single 5V power rail and accommodates the LQFP-48 thermal profile. Verify that the host controller can drive the required serial communication protocol.

Part Context

This part belongs to the AD1833A family of audio DACs. It serves as a specialized solution for converting high-resolution digital audio streams into analog signals for professional and consumer audio hardware.

Replacement Considerations

Check for updated revisions within the AD1833A series or newer Analog Devices audio DAC families. Verify pin compatibility and software register mapping before substituting.
