APPLICATIONS
One of the main features of the device is that supply voltages (V1+,
V1-) need not be balanced, as in the following diagrams. For proper
operation, however, negative supply (V1-) 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
(V1+ and V1-) 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.
