Electronics Help Care Amplifier circuit diagram Amplifier circuit using TDA2030:
This is the amplifier circuit using TDA2030. We can also use TDA2040 and TDA2050. TDA2006. Many ICs can use this diagram; 2030 AND 2050 are popular ICs. Both diagrams are mono. In this diagram, we can use a 10-0-10 voltage to an 18-0-18 voltage. The voltage depends on the IC quality. The output power is 10 watts to 50 watts, depending on IC quality.
Amplifier circuit diagram using TDA2005:
This is an amplifier circuit diagram using TDA2005. It’s a complete audio circuit board. mono board. This board can make 25 watts in bridge mode. 12-volt-operated audio board. It’s also with a pre-amplifier and bass treble controller. Here are 3 adjustable volumes: 1st one for the main volume, 2nd for the Treble, and another for the Bass.
This is the 5.1 Channel Hi-Fi Amplifier circuit diagram made in the USA. This circuit is designed for a home theater system, featuring two front speakers, two rear speakers, one center speaker, and one subwoofer speaker. If we use a Dolby input sound card, we can get Dolby surround output. for the surround speaker, LM1875. And for the subwoofer, a TDA7294 was used.
