Hello Gerald Thank you for the input.
I understand that the design nominal is 1.8V given the subsystem's supply voltage, but am concerned about transients which may exceed this, or drop below 0V.The data sheet, p. 79, "Steady State Max Voltage at all I/O Pins" says that the limits are -0.5V to supply voltage + 0.3V. Given that the ADC supply (nominal) is 1.8 volts, wouldn't this place the min. and max at -0.5 to 2.1V? What is the current limit on the ADC pins within these limits? Is there anywhere I should look to get some insight into the actual ADC input circuitry re. input protection and configuration?
