Overview
The AD74412RBCPZ-REEL, produced by Analog Devices Inc., is a quad-channel, software-configurable input/output converter. This device integrates multiple functionalities, including analog output, analog input, digital input, and resistance temperature detector (RTD) measurements, into a single chip solution. It is designed for building and process control applications and features a 16-bit, Σ-∆ analog-to-digital converter (ADC) and four configurable, 13-bit digital-to-analog converters (DACs). The device is compatible with the serial port interface (SPI) and includes a high accuracy 2.5 V internal reference to drive the DACs and the ADC.
