NOTES:

1 Full Scale Range (FSR) is 3 V 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.
