1 / 20 page  TDA2005 20W BRIDGE AMPLIFIER FOR CAR RADIO October 1998 1 2 3 4 5 6 7 9 10 11 8 BOOTSTRAP(1) INPUT-(1) SVRR GND INPUT-(2) INPUT+(2) OUTPUT(2) +VS OUTPUT(1) INPUT+(1) TAB CONNECTED TO PIN 6 D95AU318 BOOTSTRAP(2) PIN CONNECTION MULTIWATT11 ORDERING NUMBERS : TDA2005M (Bridge Appl.) TDA2005S (Stereo Appl.) ® High output power : PO = 10 + 10 W@RL =2 Ω, d = 10% ; PO = 20W@RL =4 Ω ,d = 1 %. High reliability of the chip and package with addi- tional 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 ampli- fiers with or without boostrap and with programma- ble gain and bandwidth. Space and cost saving : very low number of external components, very simple mounting sys- tem with no electrical isolation between the pack- age and the heatsink (one screw only). In addition, the circuit offers loudspeaker protec- tion during short circuit for one wire to ground. DESCRIPTION The TDA2005 is class B dual audio power amplifier in MULTIWATT ® packagespecifically designed for car radio application : power booster amplifiers are easily designed using this device that provides a high current capability (up to 3.5 A) and that can drive very low impedance loads (down to 1.6 Ω in ABSOLUTE MAXIMUM RATINGS Symbol Parameter Value Unit Vs Operating Supply Voltage 18 V Vs DC Supply Voltage 28 V Vs Peak Supply Voltage (for 50 ms) 40 V Io (*) Output Peak Current (non repetitive t = 0.1 ms) 4.5 A Io (*) Output Peak Current (repetitive f ≥ 10 Hz) 3.5 A Ptot Power Dissipation at Tcase =60 °C 30 W Tstg,Tj Storage and Junction Temperature – 40 to 150 °C (*) The max. output current is internally limited. 1/20 |
