Working Principles

The DAC8168ICPW operates by converting digital input data into corresponding analog voltages. The digital data is received through the serial data input (DIN) pin and synchronized with the serial clock input (SCLK). The converted analog voltages are then available at the respective analog output channels (OUTA to OUTH). The chip select input (SYNC) is used to enable or disable the DAC. The load DAC input (LDAC) allows for simultaneous updating of all output channels.
