Hi,
During power-up of the device the analog input pins (ADC1Ax, ADC1Bx, ADC2Ax, ADC2Bx, ADC1VREFHI, ADC2VREFHI) of the Concerto MCU are powered but the Concerto MCU is not yet powered by 3.3V. (up to 100ms)
How should we deal with this operating case ?
Is there an Application note that describes this situation and how to protect the analog input (ADC1Ax, ADC1Bx, ADC2Ax, ADC2Bx) and the ADCxVREF pins ?
Thanks in advance,
Jo
