® TDA7384A 4 x 35W QUAD BRIDGE CAR RADIO AMPLIFIER HIGH OUTPUT POWER CAPABILITY: 4 x 40W/4 MAX. 4 x 35W/4 EIAJ 4 x 25W/4 @ 14.4V, 1KHz, 10% 4 x 22W/4 @ 13.2V, 1KHz, 10% LOW DISTORTION LOW OUTPUT NOISE ST-BY FUNCTION MUTE FUNCTION AUTOMUTE AT MIN. SUPPLY VOLTAGE DETECTION LOW EXTERNAL COMPONENT COUNT: ­ INTERNALLY FIXED GAIN (26dB) ­ NO EXTERNAL COMPENSATION ­ NO BOOTSTRAP CAPACITORS PROTECTIONS: OUTPUT SHORT CIRCUIT TO GND, TO VS, ACROSS THE LOAD VERY INDUCTIVE LOADS OVERRATING CHIP TEMPERATURE WITH SOFT THERMAL LIMITER LOAD DUMP VOLTAGE BLOCK AND APPLICATION DIAGRAM Vcc1 Vcc2 FLEXIWATT25 ORDERING NUMBER: TDA7384A FORTUITOUS OPEN GND REVERSED BATTERY ESD DESCRIPTION The TDA7384A is a new technology class AB Audio Power Amplifier in Flexiwatt 25 package designed for high end car radio applications. Thanks to the fully complementary PNP/NPN output configuration the TDA7384A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets. 470µF ST-BY N.C.
