TDA2005
20W BRIDGE AMPLIFIER FOR CAR RADIO

High output power : PO = 10 + 10 W@RL = 2, d = 10% ; PO = 20W@RL = 4 , d = 1 %. High reliability of the chip and package with additional complete safety during operation thanks to protection against : OUTPUT DC AND AC SHORT CIRCUIT TO GROUND OVERRATING CHIP TEMPERATURE LOAD DUMP VOLTAGE SURGE FORTUITOUS OPEN GROUND VERY INDUCTIVE LOADS Flexibility in use : bridge or stereo booster amplifiers with or without boostrap and with programmable gain and bandwidth. Space and cost saving : very low number of external components, very simple mounting system with no electrical isolation between the package and the heatsink (one screw only). In addition, the circuit offers loudspeaker protection during short circuit for one wire to ground.
