20w Bridged Amplifier With Tda2005M

TDA2005 is a 20W is a bridge amplifier for car radio. The TDA 2005 is classB dual audio power amplifier in MULTIWATT) package specifically 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 1.6W).

TDA 2005 maximum ratings

•Operating Supply Voltage 18 V •DC Supply Voltage 28 V •Peak Supply Voltage (for 50 ms) 40 V •Output Peak Current (non repetitive t = 0.1 ms) 4.5 A •Output Peak Current (repetitive f . 10 Hz) 3.5 A •Power Dissipation at Tcase = 60 °C 30 W •Storage and Junction Temperature – 40 to 150 °C

TDA2005M is designed for bridge applications and TDA2005S for stereo application. With TDA 2005S you can build a 2 x 10Watt stereo amplifier circuit on 2 x 2Ω speakers with 10% distorsions.
