Working Principles

The DAC2904IPFB operates by converting digital input data into corresponding analog voltages. It utilizes a 12-bit resolution to provide precise control over the analog output. The digital input is received through the serial data input (DIN) pin, synchronized with the serial clock (SCLK) input, and selected using the chip select (SYNC) pin. The converted analog outputs are available on channels A, B, C, and D.
