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
