DAC (AD5662) component

16-bit external DAC connected to the microcontroller using SPI.

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:
