Hi Team,
I have two quick questions regarding AMC7812's ADC.
(1) Only CH0~CH4 can be configured as differential input. I'm confused with its full scale input voltage -2xVref~2xVref. Does it mean that the scenario that VIN+ (CH0 pin) is applied with +4V and VIN- is applied with -4V (CH1 pin) is acceptable? I'm not sure if it's OK or if there's any possibility of pin damage because AVDD is 5V in regard to GND.
(2) For LSB with ADGn = 1 (2xVref), could you check if the calculation below is correct?
Single ended (0~2xVref) : LSB = Vrefx2/2^resolution = 2.5Vx2/2^12 = 1.2mV
Differential (-2xVref ~ 2xVref) : LSB = 2xVrefx2/2^resolution = 2x2.5Vx2/2^12 = 0.6mV
Thank you!
