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 (3 5A) enables the de-
vice to deliver 10W channel into 2X (LM2005T-S) or 20W
bridged monaural (LM2005T-M) into 4X with low distortion
Features
Y Wide supply range (8V – 18V)
Y Externally programmable gain
Y With or without bootstrap
Y Low distortion
Y Low noise
Y High peak current capability
Y POe20W bridge
Y High voltage protection
Y AC and DC output short circuit protection to ground or
across load
Y Thermal protection
Y Inductive load protection
Y Accidental open ground protection
Y Immunity to 40V power supply transients
Y 3 C W device dissipation
Y Pin for pin compatible with TDA2005
