USAGE NOTES

* Please avoid the short-circuits to VCC, ground, or load short-circuit.

* Please connect the cooling fin with the GND potential.

* The thermal shutdown circuit operates at about TJ=150 . However, the thermal shutdown circuit is reset

automatically if the temperature drops.

* Please carefully design the heat radiation especially when you take out high power at high VCC .

* Please connect only the ground of signal with the signal GND of the amplifier in the previous stage.
