Can the ADS1115 be damaged by an input voltage on A0-A3 that over ranges the current programmable gain setting?
The voltages on the inputs will never exceed VCC +.3v or GND - .3v. This of course would damage the part per the data sheet.
An example would be a differential input of 4.200 volts while the gain is set to 16. None of the input voltages will ever exceed 5.00 V (Vcc) or go below 0 V (Gnd).
Differential inputs A0-A1 - Signal 4.200 V Gain 2/3
Differential inputs A2-A3 - Signal 0.25 V Gain 16
I am thinking about an application that would change the gain setting on the fly for the two measurements. When the converter would be at gain = 16 to read the A2-A3 inputs, the A0-A1 inputs would be over ranged. It would be reasonable to not have a valid digital output on the A0-A1 channel until the gain was set to 2/3. If this is acceptable usage of the ADS1115, how long will it take to recover from the over range condition and return an accurate digital conversion of the 4.200 V input on A0-A1?
