ADAU1966WBSTZRL

Digital To Analog Converters Overview

The ADAU1966WBSTZRL is a 16-channel high-performance differential output DAC from Analog Devices Inc. It utilizes a multibit sigma-delta architecture to support sample rates up to 192 kHz with 24-bit resolution. Key electrical specifications include an A-weighted dynamic range of 118 dB and total harmonic distortion plus noise (THD+N) of -98 dB at full scale. The device operates on separate 5 V analog, 2.5 V digital, and 3.3 V or 5 V I/O supplies, consuming 521 mW in normal operation. It features integrated PLL, volume control, and a temperature sensor within an 80-lead LQFP package.

Digital To Analog Converters Procurement Notes

Verify the component against the official Analog Devices datasheet Rev. E. Confirm that the 80-lead LQFP package matches the required footprint. Ensure supply voltages align with the specified 5 V analog, 2.5 V digital, and 3.3/5 V I/O requirements. Check for automotive qualification status if operating in harsh environments.

Digital To Analog Converters Selection Notes

Select this component when a high channel count with differential outputs is required. It is suitable for applications needing low propagation delay modes at 192 kHz. Consider the integrated PLL capability if master clock distribution needs to be minimized. Verify thermal resistance parameters for the 80-lead LQFP package during PCB layout.
