I used the ADS8860 in a circuit that's actually working very well except that it was noticed that the input voltage to the ADS8860 ADC can possibly exceed VREF + 0.3V.
There is a 1K resistor between the output of an opamp and Vin input of the ADS8860. VREF is 2.5V and AVDD = DVDD = 3.3V.
The output of the opamp could possibly go to 3.3V.
Is there any chance that the ADS8860 can be damaged if the output of the driving opamp goes to 3.3V since 3.3V is greater than VREF+0.3V (2.8V)?
The schematic is attached below.
