3.12 3.3V Voltage Reference

The development board features a high-precision buffered voltage reference for 3.3V, MCP1501T-33E/CHY, in an 6-Lead SOT-23 package supplied from 5V power input. This precision voltage is connected to the external voltage reference pin (ADC_VREFH) of the ADC module from the MCU. For additional information about the precision voltage reference, refer to the “MCP1501 Data Sheet” (DS20005474) available at product webpage.
