Will appreciate anyone that can clarify the following about K82 Voltage Reference for DAC module.
Datasheet page 52 Note 1 says:
"The DAC reference can be selected to be VDDA or VREFH."
But reference manual page 1429 (46.1.3 12-Bit DAC Reference) says:
"For this device VREF_OUT and VDDA are selectable as the DAC reference.
VREF_OUT is connected to the DACREF_1 input and VDDA is connected to the
DACREF_2 input. Use DACx_C0[DACRFS] control bit to select between these two
I need to use a precision 2.5V reference, should I then connect the Reference Output to VDDA? and leave VREFH floating, I cannot see how to select the VREFH for DAC, for ADC there is the SC register.
Thank you in advance,
