ADAU1962WBSTZRL

Digital To Analog Converters Overview

The ADAU1962WBSTZRL is a high-performance, single-chip digital-to-analog converter (DAC) featuring 12 differential voltage outputs. Utilizing Analog Devices' patented multibit sigma-delta architecture, it supports 24-bit resolution and sample rates from 32 kHz to 192 kHz. The device operates with 5 V analog supplies (AVDDx), 2.5 V digital supplies (DVDD/PLLVDD), and 3.3 V or 5 V I/O supplies (IOVDD). It includes an on-chip linear regulator driver to generate the digital supply from the analog rail. Key specifications include 118 dB dynamic range, -98 dB THD+N, and low electromagnetic interference design.

Digital To Analog Converters Procurement Notes

Verify the specific suffix WBSTZRL against the manufacturer's current ordering guide to confirm package type, temperature grade, and reel specifications. Ensure compatibility with automotive qualification standards if required for the target application. Cross-reference pinout details in the latest datasheet revision A to avoid integration errors.

Digital To Analog Converters Selection Notes

Select this component for applications requiring multiple differential audio channels without external DACs. The integrated linear regulator simplifies power design by deriving DVDD from AVDD. Consider the 80-lead LQFP package size and thermal resistance of 42.3°C/W for PCB layout. Verify that the system can accommodate the 5 V analog supply requirement.
