TDA2020

LINEAR INTEGRATED CIRCUIT 20W Hi-Fi AUDIO AMPLIFIER The TDA 2020 is a monolithic integrated operational amplifier in a 14-lead quad in-line plastic package, intended for use as a low frequency class B power amplifier. Typically it provides 20W output power (d = 1%) at ± 18V/4n; the guaranteed output power at ± 17V/4n. is 15W (DIN norm 45500). The TDA 2020 provides high output current (up to 3.5 A) 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 ~o as to keep to working point of the output transistors within their safe operating area. A conventional thermal shut-down system is also included.
