Product Summary
The TDA2040 is a monolithic integrated circuit in Pentawatt package,intended for use as an audio class AB amplifier. Typically it provides22W output power (d = 0.5%) at Vs = 32V/4W . The TDA2040 provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates a patented short circuit protection system comprising an arrangement for automaticallylimiting the dissipatedpowersoas to keep the working point of the output transistors within their safe operating area. A thermal shut-down system is also included.
