Working Principles

The CDCF5801ADBQR utilizes advanced digital signal processing techniques to convert digital input signals into precise analog outputs. It employs a 16-bit resolution to achieve high accuracy in the conversion process. The IC operates by receiving digital data through the serial interface (SCLK, SDATA) and synchronizing it with the frame synchronization input (FS). The converted analog signals are then available at the four analog output pins (OUTA, OUTB, OUTC, OUTD).
