To calculate the maximum junction temperature or heat sink required, use the thermal resistance values which follow the Equivalent Circuit Schematic. Note 2: For a supply voltage less than 30V between V a and V b, the absolute maximum input voltage is equal to the supply voltage. Note 3: For military electrical specifications RETS759X are available for LM759H.

With g15V power supplies, the LM759 can dissipate up to 540 mW in its quiescent (no load) state. This would result in a 100 §C rise in chip temper- ature to 125 §C (assuming a 25 §C ambient temperature). In order to avoid this problem, it is advisable to use either a slip on or stud mount heat sink with this package. If a stud mount heat sink is used, it may be necessary to use insulat- ing washers between the stud and the chassis because the case of the LM759 is internally connected to the negative power supply terminal. Plastic Package (LM759CP/LM77000CP) The LM759CP and LM77000CP are designed to be at- tached by the tab to a heat sink. This heat sink can be either one of the many heat sinks which are commercially avail- able, a piece of metal such as the equipment chassis, or a suitable amount of copper foil as on a double sided PC board. The important thing to remember is that the negative power supply connection to the op amp must be made through the tab. Furthermore, adequate heat sinking must be provided to keep the chip temperature below 125 §C un- der worst case load and ambient temperature conditions.
