SHAOXING SILICORE TECHNOLOGY CO.,LTD www. Silicore. com. cn CHMC 14W Hi-Fi AUDIO AMPLIFIER D2030 G E N E R A L D E S C R I P T I O N Outline Drawing The D2030 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 Ω;at ±14V or 28V, the guaranteed output power is 12W on a 4Ω load and 8W on a 8 Ω (DIN45500). The D2030 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 automa tically limiting the dissipated power so as to keep the working point of the output transistors within thei r safe operating area. A conventional thermal shut-down system is also included. TYPICAL APPLICATION 1.0uF 4.7K 2uF 150K 100K Ra 100K 100uF 100nF Rb 100K Cb 22uF 1N4001 1N4001 2000uF 220nF Vi +Vs R 2 3 L D2030 22K
