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.
Multiwatt11
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.
