Working Principles

The CAT1161WI25 is a digital-to-analog converter that converts binary digital signals into corresponding analog voltage levels. It utilizes a 12-bit resolution to provide precise conversion accuracy. The IC operates by receiving digital input data through the DIN pin, which is then converted into an analog voltage at the VOUT pin. The reference voltage, provided either internally or externally through the REF pin, determines the maximum output voltage range. The conversion process is controlled by the serial clock (SCLK) and chip select (CS) inputs.
