Full Scale Range (FSR) is 10V for unipolar mode.
Guaranteed but not production tested.
Digital input levels should not go below ground or exceed the positive supply voltage, otherwise damage may occur.
See timing diagram.
Specified values guarantee functionality. Refer to other parameters for accuracy.
