14W Hi-Fi AUDIO AMPLIFIER
DESCRIPTION The TDA2030 is a monolithic integrated circuit in Pentawatt® package, intended for use as a low frequency class AB amplifier. Typically it provides 14W output power (d = 0.5%) at 14V/4; at ± 14V the guaranteed output power is 12W on a 4 load and 8W on a 8 (DIN45500). The TDA2030 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 shut-down system is also included. ABSOLUTE MAXIMUM RATINGS
