DigiVref Click Board

The DigiVref Click Board™ is a very precise voltage reference Click Board™, which allows one of four different voltage values to be selected over the SPI interface. Once the selection is done, the voltage reference stays fixed, even when the SPI interface is completely disconnected. The voltage reference is buffered by an operational amplifier, and thus it is very stable. Thanks to the MCP1541, a high precision voltage reference IC, and high thermal stability used resistors, the output voltage remains highly regulated, keeping the thermal drift very low. It can be used whenever a precise voltage reference is required
