Overview
The AD1939WBSTZ is a high-performance, single-chip codec produced by Analog Devices Inc. This integrated circuit features four analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs) with differential output. It utilizes Analog Devices' patented multibit sigma-delta (Σ-Δ) architecture and operates at a maximum sample rate of 192 kHz with a 24-bit resolution. The device includes an SPI port for microcontroller interface, allowing adjustments to volume and other parameters. It is designed for low Electromagnetic Interference (EMI) and operates from a single 3.3 V supply, with tolerance for 5 V logic inputs.
