3.1.8 Analog Voltage Reference Header

The analog subsystem of the F280013x allows for flexible voltage reference sources. The ADC modules are referenced to the VREFHIx and VREFLOx pin voltages. VREFHIx can either be driven externally or can be generated by an internal bandgap voltage reference. An external voltage can be supplied to header J15 as an external voltage source for VREFHIx. Note that there is no signal conditioning circuitry in place for the voltage reference. For best performance, some additional circuitry may be required.
