TDA2004A Datasheet | STMicroelectronics

features are : Low distortion. Low noise. High reliability of the chip and of the package with additional safety during operation thanks to protections against : OUTPUT AC SHORT CIRCUIT TO GROUND VERY INDUCTIVE LOADS OVERRATING CHIP TEMPERATURE LOAD DUMP VOLTAGE SURGE FORTUITOUS OPEN GROUND Space and cost saving : very low number of external ponents, very simple mounting system with no electrical isolation between the package and the heatsink. . . . . . MULTIWATT11 ORDERING NUMBER : TDA2004A DESCRIPTION The TDA2004A is a class B dual audio power amplifier in MULTIWATT® package specifically desi- gned for car radio applications ; stereoamplifiers 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 1.6Ω ).
