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.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
