ADAU1328BSTZ-RL

Overview

The ADAU1328BSTZ-RL is a high-performance audio codec manufactured by Analog Devices Inc. It integrates two differential analog-to-digital converters (ADCs) and eight single-ended digital-to-analog converters (DACs). The device supports sample rates from 8 kHz to 192 kHz with 24-bit resolution. It operates on a single 3.3 V supply, featuring an internal phase-locked loop (PLL) for clock generation. Key performance metrics include a dynamic range of 107 dB for ADCs and 108 dB for DACs, with total harmonic distortion plus noise of -94 dB. The component utilizes a 48-lead LQFP package.

Feature Summary

• Integrates an on-chip PLL to generate master clocks from LRCLK or external crystals, eliminating the need for separate high-frequency clock sources.
• Designed for low electromagnetic interference (EMI) through continuous-time architectures and optimized power consumption at 3.3 V.
• Features software-controllable clickless mute, log volume control with autoramp, and independent channel attenuation.
• Supports multiple serial data formats including I2S, left justified, right justified, and time-division multiplexing (TDM).

Applications

• Home theater systems
• Set-top boxes
• Digital audio effects processors

Procurement Notes

Verify the specific suffix BSTZ against the manufacturer's ordering guide to confirm the package type and tape-and-reel configuration. Confirm RoHS compliance status and lead-free specifications directly with Analog Devices or authorized distributors prior to procurement.

Selection Notes

Select this component for applications requiring multi-channel output with differential stereo inputs. Ensure the design accommodates the 48-lead LQFP footprint and provides adequate thermal dissipation. Verify that the system logic levels are compatible with the 3.3 V digital interface requirements.

Part Context

This part belongs to the ADAU1328 family of audio codecs. It is distinguished by its single-ended DAC output configuration housed in a 48-lead LQFP package. Other variants in the family may offer differential DAC outputs or different packaging options.

Replacement Considerations

Consult the official Analog Devices datasheet for verified substitute part numbers within the same product family. Cross-reference pinouts and electrical specifications carefully before implementation.
