Overview
The ADAU1962WBSTZ, produced by Analog Devices Inc., is a high-performance, single-chip digital-to-analog converter (DAC) that offers 12 DAC channels with differential or single-ended outputs. This device utilizes Analog Devices' patented multibit sigma-delta (Σ-Δ) architecture, ensuring high-quality audio conversion. The ADAU1962WBSTZ is designed to operate with low electromagnetic interference (EMI) and features a built-in phase-locked loop (PLL) to derive the internal master clock from an external left-right frame clock (LRCLK), eliminating the need for a separate high-frequency master clock. It supports various audio interfaces, including SPI and I2C, allowing for flexible control by a microcontroller.
