A monolithic power amplifier IC intended for use as a high quality, class AB audio power amplifier.Typically it provides 22W output power into 4 with 0.5% distortion, from a 32V supply. The device is |
| designed to operate from a split power supply and no electrical isolation is needed between the mounting tab and its heatsink. It provides a high output current and has very low harmonic and crossover distortion. The device incorporates a patented short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. Thus the TDA2040V is protected against temporary overloads or short-circuit. A thermal shutdown system is also included, and should the short-circuit exist for a longer time, the thermal shutdown protection keeps the junction temperature within safe limits. The device's pins are arranged for vertical PCB mounting. |
