RM57L843: Unused ADC

Federico Silva

Part Number: RM57L843

Hi,

I'm currently not using the ADC of the RM57. I wanted to know if not connecting VCCAD (or grounding it) would cause any issue, as I don't find that information on the datasheet.

Thanks,

Federico

Even if you don't plan to use the on-chip ADC in your application, the ADC reference and operating supplies should still be within the recommended operating range. The ADC does not draw current from the ADREFHI unless it is performing conversions.
