USAGE NOTES
* Please avoid the short-circuits to V
CC
, ground, or load short-circuit.
* Please connect the cooling fin with the GND potential.
* The thermal shutdown circuit operates at about T
J
=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 V
CC
.
* Please connect only the ground of signal with the signal GND of the amplifier in the previous stage.
