LM2005 20 Watt Automotive Power Amplifier

General Description

The LM2005 is a dual high power amplifier designed to

deliver optimum performance and reliability for automotive

applications High current capability (35A) enables the de-

vice to deliver 10Wchannel into 2X (LM2005T-S) or 20W

bridged monaural (LM2005T-M) into 4X with low distortion
