Overview
The AD1974YSTZ, produced by Analog Devices Inc., is a high-performance, single-chip analog-to-digital converter (ADC) that integrates four ADCs with differential inputs. It utilizes Analog Devices' patented multibit sigma-delta (Σ-Δ) architecture. This device is designed for low electromagnetic interference (EMI) and operates from a single 3.3V supply. The AD1974YSTZ includes an SPI port, enabling microcontroller control for various parameters such as mute and power-down functions.
