Amplifier circuit diagram using tda2030: Amplifier circuit diagram using tda2030. this is a 14 watts 4-ohms audio amplifier. this circuit can run with 6-0-6 to 18-0-18 voltage. here need dual voltage positive negative and the ground voltage. normally this circuit is used in the 2.1 sound system. it’s a mono …

TEA2025B amplifier circuit: This is a mini 5 watts + 5 watts TEA2025B amplifier circuit diagram. here used TEA2025 ic. this IC can make 5 watts for each channel in stereo mode. we can use 6 voltage to 15 voltage maximum. this circuit is a stereo circuit. this IC can …

How to make stereo amplifier : This is a 2.0 amplifier circuit diagram. this is a bridge mode circuit. this circuit is based on STA540. this IC has 4 inputs and 4 outputs. but here it’s made in bridge mode. now it’s a stereo circuit. Right and Left speakers. this …

how to make the sound booster? This is a sound booster circuit diagram. this circuit boosts the sound. It’s also like a pre-amplifier. sometimes we need to increase the sound. that time we need this circuit. we also can use this circuit for the headphone to increase the sound. some …

How to make a small amplifier circuit: This is a small amplifier circuit diagram. it’s 10 watts. this circuit run with 12 voltage to 15 voltage. this circuit used TDA2003. this is the mono-circuit diagram. if we need stereo then we have to use a dual circuit. One circuit for …

How to make a small amplifier: This is the circuit diagram for 20watts using tda2030. These chips run a 4Ω speaker at 18W or an 8Ω speaker at 14W. this circuit diagram runs with positive negative and ground voltage. we can use a maximum of 15-0-15 voltage. 12-0-12 voltage is …

Headphone amplifier: This is a Headphone amplifier circuit diagram. sometimes we need an amplifier for our headphones because of the low sound volume. some tv has no headphone output line. there have only one audio pre-out for another amplifier. there we need this circuit diagram. this circuit runs with 5 …

Speaker protection circuit diagram: This is a Speaker protection circuit diagram for our amplifier. this circuit can save our speaker from unwanted burning. Maximum original amplifier got this circuit with amplifier section or power section. but when we make an amplifier using a local circuit, we have to use this …
