TDA2004R
10 + 10 W stereo amplifier for car radio
Features Low distortion Low noise Protection against: Output AC short circuit to ground Overrating chip temperature Load dump voltage surge Fortuitous open ground Very inductive loads
Description
The TDA2004R is a class B dual audio power
amplifier in Multiwatt11 package specifically
designed for car radio applications.
Power booster amplifiers can be easily designed
using this device that provides a high current
capability (up to 3.5 A) and can drive very low
impedance loads (down to 1.6 ).
The TDA2004R allows very compact applications
because few external components are required
and it doesn't need electrical insulation between
the package and the heatsink.
