ADAU1962AWBSTZ-RL

Digital To Analog Converters Overview

The ADAU1962AWBSTZ-RL is a high-performance, single-chip digital-to-analog converter (DAC) featuring 12 channels with differential or single-ended voltage outputs. It utilizes a multibit sigma-delta architecture and operates from 2.5 V digital and 3.3 V analog supplies. Key electrical specifications include a dynamic range of 114 dB (A-weighted, differential) and -97 dB THD+N at room temperature. The device supports sample rates up to 192 kHz with 24-bit resolution and includes an integrated linear regulator driver for the digital supply. It is housed in an 80-lead LQFP package.

Digital To Analog Converters Feature Summary

• 12-channel DAC with 114 dB dynamic range (differential) and -97 dB THD+N
• Supports 24-bit resolution and sample rates from 32 kHz to 192 kHz
• Integrated PLL for clock generation and low EMI design
• SPI/I²C control interface with software-controllable volume and mute functions

Digital To Analog Converters Applications

• Automotive audio systems
• Home theater systems
• Digital audio effects processors

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'WBSTZ-RL' against the manufacturer's current ordering guide to confirm tape-and-reel packaging and automotive qualification status. Ensure compatibility with the required 80-lead LQFP footprint and check for any recent RoHS compliance updates in the latest datasheet revision.

Digital To Analog Converters Selection Notes

Select this component when a multi-channel, high-fidelity DAC is required with low electromagnetic interference characteristics. The integrated PLL allows operation without a separate master clock source if derived from LRCLK. Verify that the system can accommodate the 2.5 V digital and 3.3 V analog supply requirements and the 80-lead LQFP package constraints.

Digital To Analog Converters Part Context

This part belongs to the ADAU1962A family of high-performance audio DACs. The 'W' indicates automotive qualification under AEC-Q100 standards. The 'BSTZ' denotes the 80-lead LQFP package with lead-free termination. The '-RL' suffix specifies the reel packaging format for automated surface-mount assembly.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family are limited by the specific 12-channel configuration and automotive grade. Check for updated revisions of the ADAU1962A series. Other Analog Devices multi-channel DACs may require significant schematic and layout modifications due to differences in pinout, power supply requirements, or control interfaces.
