Working Principles

The AD977CRSZ is a digital-to-analog converter that operates by converting binary digital signals into corresponding analog voltages. It utilizes a 16-bit resolution to accurately represent the digital input, providing a high level of detail in the analog output. The IC receives digital data through the SDATA pin, which is synchronized with the clock signal provided on the SCLK pin. The converted analog signal is then available at the VOUTA and VOUTB pins.
