4. For operating at high temperatures, the AP358 must be derated based on a +125°C maximum junction temperature and a

thermal resistance of 120°C/W for DIP and 189°C/W for Small Outline package, which applies for the device soldered in a

printed circuit board, operating in a still air ambient. The dissipation is the total of both amplifiers—use external resistors,

where possible, to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit.

5. Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits

to ground, the maximum output current is approximately 40mA independent of the magnitude of V+. At values of supply

voltage in excess of +15V, continuous short-circuits can exceed the power dissipation ratings and cause eventual

destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.

Note:

6. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base

junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this

diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output

voltages of the op amps to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is

driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was

negative, again returns to a value greater than -0.3V (at 25°C).
