PA7522
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 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.
