Overview
The ADAU1966WBSTZRL, produced by Analog Devices Inc., is a high-performance, single-chip digital-to-analog converter (DAC) that provides 16 DAC channels with differential output. This device utilizes Analog Devices' patented multibit sigma-delta (Σ-Δ) architecture, ensuring high-quality audio conversion. The ADAU1966WBSTZRL operates with 2.5 V digital, 5 V analog, and 3.3 V or 5 V input/output supplies, and it includes a linear regulator to generate the digital supply voltage from the analog supply voltage. The device is designed for low electromagnetic interference (EMI) and is available in an 80-lead LQFP package.
