Working Principles

The AD7537JPZ-REEL operates based on the principle of binary-weighted resistor ladder network. It uses a combination of switches and resistors to convert the digital input into an analog output voltage. The digital data is applied to the input pins, and the corresponding resistors are switched on or off based on the binary value. The resulting analog voltage is then available at the VOUT pin.
