APPLICATIONS

One of the main features of the device is that supply voltages (V+,

V-) need not be balanced, as in the following diagrams. For proper

operation, however, negative supply (V-) should always be at least

6V more than the ground terminal (pin 6). Input Common-Mode

range should be limited to values of 2V less than the supply voltages

(V+ and V-) up to a maximum of

±5V as supply voltages are

increased.

It is also important to note that Output A is in phase with Input A and

Output B is in phase with Input B.
