Part Details:

® TDA2040 20W Hi-Fi AUDIO POWER AMPLIFIER DESCRIPTION The TDA2040 is a monolithic integrated circuit inPentawatt ® package, intended for use as an audioclass AB amplifier. Typically it provides 22W outputpower (d = 0.5%) at Vs = 32V/4 . The TDA2040provides high output current and has very lowharmonic and cross-over distortion. Further thedevice incorporates a patented short circuit protec- PENTAWATT tion system comprising an arrangement for auto-matically limiting the dissipated power so as to keep ORDERING NUMBER : TDA2040V the working point of the output transistors withintheir safe operating area. A thermal shut-downsystem is also included.
