8-channel: 16-bit: 200mA current output DAC reference design

Description

This reference design combines the small size and high performance of the DAC80508 8-channel: 16-bit digital-to-analog converter (DAC) with precision op-amps to create a high-density and accurate current-source solution. The reference design has an maximum output current of 200 mA and allows for a minimal PVDD supply voltage to reduce power consumption for high efficiency. It also features a low current-noise output due to the low reference-voltage noise of the DAC80508 and low voltage and current noise of the OPA2376.
