The TDA2040 is a monolithic integrated circuit in Pentawatt Ò package, intended for use as an audio class AB amplifier. Typically it provides 22W output power (d = 0.5%) at Vs = 32V/4W . The TDA2040provides high output current and has very lowharmonic and cross-over distortion. Further thedevice incorporates a patented short circuit protectionsystem comprising an arrangement for automaticallylimiting the dissipated power so as to keepthe working point of the output transistors within their safe operating area. A thermal shut-down system is also included.
