TDA2040 amplifier circuit diagram 30W

TDA2040 amplifier circuit diagram 30W. The TDA2040 is a monolithic integrated circuit in Pentawatt  package, intended for use as an audio class AB amplifier. Typically it provides 22W output power (d = 0.5%) at Vs = 32V/4Ω. 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 automatically limiting the dissipated power to keep the working point of the output transistors within their safe operating area. A thermal shut-down system is also included.
