Working Principles

The TLV5627IPWR operates by converting digital input data into corresponding analog voltages. It utilizes an internal reference voltage (VREF) to determine the output voltage range. The digital input data is received through the serial interface (DIN) and clocked in using the serial clock input (SCLK). The chip select input (SYNC) enables or disables the DAC operation. The load DAC input (LDAC) allows simultaneous update of both channels.
