ADAU1966AWBSTZ

Digital To Analog Converters Overview

The ADAU1966AWBSTZ is a high-performance, single-chip digital-to-analog converter (DAC) featuring 16 channels with differential or single-ended voltage outputs. Utilizing Analog Devices' patented multibit sigma-delta architecture, it supports sample rates from 32 kHz to 192 kHz at 24-bit resolution. The device operates on 2.5 V digital and 3.3 V analog supplies, consuming 299 mW quiescent power. It includes an integrated PLL for clock generation, a linear regulator driver, and a temperature sensor. Key performance metrics include 114 dB dynamic range (differential, A-weighted) and -97 dB THD+N (differential).

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'WBSTZ' against the manufacturer's current ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with automotive qualification requirements if applicable, as the device family is qualified for such applications. Cross-reference pinout details with the latest datasheet revision to avoid integration errors.

Digital To Analog Converters Selection Notes

Select this component for designs requiring up to 16 synchronized audio channels with low propagation delay options. Verify that the system can provide the required 3.3 V analog and 2.5 V digital supply rails. Consider the 80-lead LQFP package constraints for PCB layout. Evaluate the need for the integrated PLL versus external clock sources based on EMI sensitivity.

Digital To Analog Converters Part Context

The ADAU1966A belongs to a series of high-performance audio DACs from Analog Devices. The 'W' in the part number typically denotes a specific temperature range or packaging variant within the product line, while 'BSTZ' indicates the 80-lead LQFP package with lead-free termination. This model is designed for multi-channel audio processing where space and power efficiency are critical.

Digital To Analog Converters Replacement Considerations

Direct replacements should be sought within the ADAU1966A family or other 16-channel sigma-delta DACs from Analog Devices. Verify pin compatibility and register map similarities if substituting with other models in the same series. Check for any changes in supply voltage requirements or package dimensions.
