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