Detailed description
Overview
The AD5662 is a 3V/5V general purpose SPI compatible, high-resolution digital to analog converter (DAC), capable of generating a rail-to-rail voltage output.
With 16-Bit resolution, the AD5662 is capable of finely tuning the voltage output across 65,536 steps, with an individual step voltage of 5/65536 = 0.0000763 volts DC.
The AD5662 requires an external reference voltage to set the output range of the DAC.
Pin reference from the datasheet:
Circuit Diagram
Examples
This example reads a potentiometer that is connected across the supply voltage. The output from the DAC should mimic the voltage that's across ADC pin & GND.
