Working Principles
The SCH3221I-7U-TR 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 and accuracy in the conversion process. The IC operates by taking in a serial data input (DIN) along with clock (SCLK) and chip select (CS) signals. The digital input is then converted into an analog output voltage (VOUT) proportional to the input value. The reference voltage (REF) determines the maximum output voltage, which is adjustable within the specified range.
