Overview
The ADAU1966WBSTZ is a high-performance, single-chip digital-to-analog converter (DAC) produced by Analog Devices Inc. This component features 16 digital-to-analog converters with differential output, utilizing Analog Devices' patented multibit sigma-delta (Σ-Δ) architecture. It is designed for low EMI and operates from 2.5 V digital, 5 V analog, and 3.3 V or 5 V input/output supplies. The ADAU1966 includes an SPI/I²C port for microcontroller control, allowing adjustments to volume and other parameters. It is available in an 80-lead LQFP package and supports sample rates from 32 kHz to 192 kHz.
