TDA2030 14w hi-fi audio amplifier TDA2030 general description outline drawing the tda 2030 is a monolithic integrated circuit in pentawatt package, intended for use as a low frequency class ab am plifier. ty pically it provides 14w output power (d = 0.5%) at 14v/4 ? ;at 14v or 28v, 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 harm onic and cross-over distortion. further the device incorporates an origin al (and patented) short circuit protection sy stem com p rising an arrangem e nt for autom a tically lim iting the dissipated power so as to keep the working point of the output transistors within their safe operating area. a conventional therm a l shut-down sy stem is also included. typical applica t ion c1 1. 0uf r2 4. 7k c2 2uf r1 150k r3 100k ra 100k c5 100uf c3 100nf rb 100k cb 22uf d2 1n4001 d1 1n4001 2000uf r4 1 c7 220nf vi +vs r 1 2 3 5 4 l 2030 22k 1 tiger electronic co.,ltd
