TDA2005 two-channel audio power amplifier integrated circuit

TDA2005 is a dual-channel audio power amplifier integrated circuit that operates on a single power supply. It can be used in OTL dual-channel power amplifiers and can also be connected to a BTL bridge amplifier circuit. TDA2005 contains various protection circuit links such as overheating, overload, output short circuit, etc., and its performance is stable. The appearance of TDA2005 is 11-pin unidirectional arrangement, the appearance diagram is as follows
