ADAU1962WBSTZ

Digital To Analog Converters Overview

The ADAU1962WBSTZ is a high-performance, single-chip digital-to-analog converter (DAC) featuring 12 differential output channels. Utilizing Analog Devices' patented multibit sigma-delta architecture, it supports sample rates from 32 kHz to 192 kHz with 24-bit resolution. The device operates on 5 V analog supplies and includes an internal linear regulator to generate the 2.5 V digital supply. Key specifications include a dynamic range of up to 118 dB (A-weighted), -98 dB THD+N, and low electromagnetic interference design. It integrates a temperature sensor, software-controllable mute, and volume control, housed in an 80-lead LQFP package.

Digital To Analog Converters Feature Summary

• 12-channel differential voltage DAC outputs using multibit sigma-delta architecture
• High dynamic range: 118 dB A-weighted; THD+N of -98 dB
• Integrated PLL for clock generation or direct master clock input
• Internal linear regulator driver generating 2.5 V digital supply from 5 V analog supply

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 against the manufacturer's current ordering guide to confirm package type and tape/reel configuration. Ensure compatibility with the required IOVDD voltage levels (3.3 V or 5 V) for the host system interface.

Digital To Analog Converters Selection Notes

Select this component for applications requiring multiple differential audio outputs with high fidelity. Consider the 80-lead LQFP thermal resistance (42.3°C/W) for PCB layout. Verify that the host controller supports the required SPI/I2C control protocols and serial data formats (I2S, TDM, etc.).

Digital To Analog Converters Part Context

This part belongs to the ADAU1962 family of high-performance audio DACs. It is functionally identical to the standard ADAU1962 but specified in the 80-lead LQFP package variant. The device is designed for low EMI and includes features like autoramp volume control and clickless mute.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include the ADAU1962AWBSTZ. Verify that any substitute maintains the 12-channel differential output capability and the specific 80-lead LQFP footprint.
