Working Principles

The DAC7644EB/1KG4 operates by converting digital input data into corresponding analog voltage or current outputs. It utilizes a 16-bit resolution to provide high precision conversion. The device accepts digital input signals through the DIN pins and uses an internal reference voltage (VREF) to determine the output voltage or current level. The conversion process is controlled by the SCLK (Serial Clock), SYNC (Synchronization), and CLR (Clear) pins. The LDAC (Load DAC) pin allows for simultaneous updating of all channels.
