Sorry for late 1. VDD for ADC power = 3.3V 2. Analog Input : 3.8V ( it's higher Absolute Max Rating of Datasheet) but on our schematic, analog signal is connecter through serial resistor 4.22Kohm. : (3.8V - 3.3V)/4.22Kohm = About 120uA : I read maximum allowable current for analog input pin is +/-10mA in datasheet. : Can this ADC have demage or not when 0.5V higher voltage come to analog input with about 120uA ?? That's what our customer want to know And until now we used this ADC almost 2,000 pcs, but we didn't fine any single adc demage Please let me know your opinion.
