Description
The TDA2030 is a monolithic integrated circuit in the Pentawatt ® package, intended for u as a low frequency class-AB amplifier. Typically it provides 14 W output power (d = 0.5%) at
14 V/4 Ω. At ±14 V or 28 V , the guaranteed output power is 12 W on a 4 Ω load and 8 W on an 8 Ω (DIN45500).
The TDA2030 provides high output current and has very low harmonic and crossover distortion.Furthermore, 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 operating point of the output transistors within their safe operating range. A conventional thermal shutdown system is also included.
