Application Hints

These are op amps with JFET input devices. These JFETs

have large reverse breakdown voltages from gate to source

and drain eliminating the need for clamps across the inputs.

Therefore large differential input voltages can easily be ac-

commodated without a large increase in input current. The

maximum differential input voltage is independent of the

supply voltages. However, neither of the input voltages

should be allowed to exceed the negative supply as this will

cause large currents to flow which can result in a destroyed

unit.

Exceeding the negative common-mode limit on either input

will force the output to a high state, potentially causing a
