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.
