CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. The collector of each transistor of the CA3081 and CA3082 is isolated from the substrate by an integral diode. The substrate must be
connected to a voltage which is more negative than any collector voltage in order to maintain isolation between transistors and provide
normal transistor action. To avoid undesired coupling between transistors, the substrate terminal (5) should be maintained at either DC
or signal (AC) ground. A suitable bypass capacitor can be used to establish a signal ground.
