I 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°C. 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.
