DESCRIPTION
The injection current effect control allows signals at disabled input channels to exceed the supply voltage range or go down to ground without affecting the signal of the enabled analog channel. This eliminates the need for external dioderesistor networks typically used to keep the analog channel signals within the supply voltage range.
