Working Principles

The MAX547AEMH is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide high precision output. The device operates by accepting digital input data through the serial interface (CS, SCLK, DIN) and converting it into an analog voltage at the OUT pin.

The internal reference voltage generator (REF) generates a stable reference voltage, which sets the maximum output voltage range. The LDAC pin allows for simultaneous updating of multiple DACs in multi-channel applications. The CLR pin resets the DAC to its default state.
