High Voltage Power Amplifier Circuit Diagram

12v 50 watt audio amplifier lm3876 is a high performance audio power amplifier ic from national semiconductors.

High voltage power amplifier circuit diagram. Voltage amplifiers many times are built with op amp circuits. 4558 ic audio power amplifier circuit diagram. 1600w high power amplifier circuit diagram in the buffer circuit coupled with op amp ic 4558 supplied 15vdc voltage circuit power supply you can see in the picture is flavored transistor d313 and b507. The lm3876 can deliver 50watts of output power into an 8 read more.

Initially there are two type of amplifier circuit diagram is in practical i e. The rest of the capacitors in the design also need to have an appropiate voltage rating. I designed this amplifier for an output power of about 100 150w. This circuit is given by emmanuel.

Use 20v to 60v for operating this circuit. Driver circuit using transistor mje340 mje350. In this circuit one ic 4558 and 4 power transistors are used with some discrete components. You should use a bipolar power supply with 30v.

And you need to make sure that the capacitors that you are using for filtering are rated for high voltage at least 100vac more doesn t hurt. From all principles above we have circuits applications as shown in figure 4 if you want to add the ic lm338 enabling them to be higher current. High frequency this dc voltage is converted into a high frequency ac signal. An operational amplifier often op amp or opamp is a dc coupled high gain electronic voltage amplifier with a differential input and usually a single ended output.

Then the regulator circuit inside to produce the desired voltage and current. An amplifier circuit diagram consists of a signal pick up transducer followed by small signal amplifier s a large signal amplifier and an output transducer. For use transformer it s using one transformer by one circuit mono. In this configuration an op amp produces an output potential relative to circuit ground that is typically 100 000 times larger than the potential difference between its input terminals.

Voltage amplifier circuit and power amplifier circuit. This is circuit diagram of powerful audio amplifier. High power dc regulator 4 20 volts 20 amps by lm338. So for example if we input 1v into the circuit we can get 10v as output if we set the circuit for a gain of 10.

A voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage. Linear vs switching dc power supplies in the table below is comparing various parameters of linear and switching form. This is a single channel audio amplifier circuit.
