AD1833AST

Overview

The AD1833AST is a six-channel audio digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a 24-bit resolution and supports sampling rates up to 192 kHz. The device operates on a single 5V power supply, with voltage limits ranging from 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 120 dB and a dynamic range of 107 dB. It utilizes a serial interface for data transmission and is housed in a 48-lead LQFP package. The component is designed for high-fidelity audio applications within an operating temperature range of -40°C to +85°C.

Procurement Notes

The AD1833AASTZ variant is listed as obsolete or end-of-life by distributors such as Mouser. Verification of availability for the specific AD1833AST suffix requires direct consultation with Analog Devices or authorized lifecycle management partners. Moisture sensitivity is indicated, requiring proper handling protocols during storage and assembly.

Selection Notes

Select this component when a multi-channel, high-resolution audio DAC is required. Ensure the design accommodates the 4.5 V to 5.5 V supply range and the LQFP-48 footprint. Verify that the system's microcontroller can support the required serial communication protocol for 24-bit data transfer at the desired sample rate.

Part Context

This part belongs to the AD1833A series of audio DACs. It is distinct from other ADI audio products like the AD1833AASTZ, which shares similar electrical specifications but may differ in packaging or manufacturing lot details. The AD1833AST represents a specific configuration within this family, typically associated with industrial or commercial grade temperature ranges.

Replacement Considerations

Direct pin-compatible replacements are not explicitly confirmed in public distributor listings for the exact AD1833AST suffix. Engineers should evaluate the AD1833AASTZ for functional equivalence, noting potential differences in packaging or lifecycle status. Alternative multi-channel DACs from Analog Devices or competitors may require schematic redesign.
