ADAU1966AWBSTZ-RL

Digital To Analog Converters Overview

The ADAU1966AWBSTZ-RL is a high-performance, 16-channel digital-to-analog converter (DAC) from Analog Devices. It utilizes a multibit sigma-delta architecture to provide differential or single-ended voltage outputs. The device supports sample rates up to 192 kHz with 24-bit resolution. Key electrical specifications include a dynamic range of 114 dB (A-weighted, differential) and total harmonic distortion plus noise of -97 dB. It operates on 3.3 V analog and 2.5 V digital supplies, consuming 299 mW quiescent power. The component is housed in an 80-lead LQFP package and is qualified for automotive applications under AEC-Q100 standards.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm packaging type and automotive qualification status. Ensure that the supply voltages match the required 3.3 V analog and 2.5 V digital rails. Confirm compatibility with the host system's serial interface protocols before integration.

Digital To Analog Converters Selection Notes

Select this component for designs requiring high channel count and low distortion. Verify that the PCB layout accommodates the 80-lead LQFP package. Ensure adequate thermal management as the device dissipates 299 mW. Check if the integrated linear regulator driver meets the digital supply requirements or if external regulation is needed.

Digital To Analog Converters Part Context

This part belongs to the ADAU1966A series of high-performance audio DACs. It is designed for multi-channel audio applications where low electromagnetic interference and high fidelity are critical. The device integrates digital filters, volume control, and a temperature sensor, reducing the need for external components.

Digital To Analog Converters Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as the ADAU1966AWBSTZ. Verify that any replacement maintains the same 16-channel configuration, package type, and automotive qualification level.
