DESCRIPTION

The TDA2006 is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class ºABº amplifier. At ±12V, d = 10 % typicallyit provides12W output power on a 4Ω load and 8W on a 8Ω . The TDA2006 provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates an original (and 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. A conventional thermal shutdown system is also included. The TDA2006 is pin to pin equivalent to the TDA2030.
