Description

The TDA2003LG is a single channel class AB

power amplifier which provides a high output

current capability (up to 3.5 A) with very low

harmonic and crossover distortion.

This power amplifier is protected against DC and

AC short circuits between all pins and ground,

fortuitous open ground, load dump surge up to

40 V and thermal over-range.
