Working Principles

The MAX547BCMH+TD is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide high precision conversion. The IC operates on a supply voltage ranging from 2.7V to 5.5V and features a serial interface (SPI/I2C) for easy integration with microcontrollers.

The input digital data is received through the DIN pin, while the SCLK pin controls the timing of the conversion process. The CS pin is used to select the chip for communication. The LDAC pin allows the user to synchronize the update of the DAC output voltage. The converted analog voltage is available at the OUT pin.

The MAX547BCMH+TD also includes an on-chip reference voltage generator, which provides a stable and accurate reference voltage for the conversion process. This eliminates the need for an external reference voltage source.
