Other Parts Discussed in Thread: OPA320
I would like to use the internal ADC and DAC of the F28388S together (one channel each).
1. ADC Reference Voltage: Connect 2.5V using REF5025 and OPA320 (VREFHIA).
2. Connect VREFHIB, VREFHIC, and VREFHID to AVDD.
3. Single-ended AI input to the ADCINA2 pin.
4. Connect 2.5V to VDAC using REF5025 and OPA320.
5. AO output to the DACOUTA pin.
Please review the hardware configuration above to see if there are any issues.
Thank you.
