Working Principles

The CAT1161WI45 is a digital-to-analog converter that converts binary digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide high precision output. The IC operates by taking in a digital input signal (DIN) and converting it into an analog voltage at the AOUT pin. The conversion process is controlled by the chip select (CS) and serial clock (SCLK) signals. The reference voltage (VREF) determines the maximum output voltage, which can be adjusted within the supply voltage range.
