7 W AF POWER AMPLIFIER
DESCRIPTION
‘The pPC12461H and pPC1242H are wadio power amplifiers which os especisity designed for car recto and car stereo. ‘The dovices are ancepsuleted in newly developed small packages testuring low thermat resistance, providing casy design for 2 12 load circu. At 14,4 V the devices give output power of 7 W at Ry «4 fland 11 Wat Rk, = 272
FEATURES
© High output power: Po» 7W TYP. @ Ry «4.2, THO. = 10%, Vog™ 14.4 V Por it W TYP. @ RL ~ 22, TID. = 10%, Veg" 14.4 V © High reliebiGty : of the Nip end peckage with additions! complete safety during operation thanks to protection wart, (1) Load dump woltege wrge, (2) Over rating chip temperatere (180°C). (3} Quaput DC and AC short circuit to ground of Ver, (4) Revere ingrtion. These ICy ere not custroyed oor damaged even when any of neighboring two terminals are shorted to each other. © Spree and cost saving: very tow number of exvernal components, very seeps mounting system with no electrical isolation between the peckage and the heat sink (ome screw only), © Pin orders of thew types ace symmertical cach other, which reducis the area of Printed Cirowlt Board effectively.
