LINEAR INTEGRATED CIRCUIT

DUAL 3-W BTL AUDIO

POWER AMPLIFIER

DESCRIPTION

The UTC PA7522 is an audio power amplifier IC for the

stereo system. In the BTL (balanced transformer less) method,

fewer external parts and easier design for applications are

required.

FEATURES

* 3-W output (8Ω) with supply voltage of 8V

* On-chip standby function

* On-chip volume function

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°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 V_CC

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