TDA7384A 4 x 35W QUAD BRIDGE CAR RADIO AMPLIFIER HIGH OUTPUT POWER CAPABILITY: 4 x 40W/4 Ω MAX. 4 x 35W/4 Ω EIAJ 4 x 25W/4 Ω @ 14.4V, 1KHz, 10% 4 x 22W/4 Ω @ 13.2V, 1KHz, 10% LOW DISTORTION LOW OUTPUT NOISE ST-BY FUNCTION MUTE FUNCTION AUTOMUTE AT MIN. SUPPLY VOLTAGE DE- TECTION 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 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 out- put configuration the TDA7384A allows a rail to rail output voltage swing with no need of boot- strap capacitors. The extremely reduced compo- nents count allows very compact sets.
