Operational Amplifier 2 Channels – TL072:
This is a 2-channel operational amplifier, specifically the TL072. TL072 is a high-speed, JFET-input single operational amplifier with low noise. TL072 pinout features a bipolar high-speed junction field-effect transistor. It’s a stereo amplifier. 12-volt operated circuit diagram.
Every amplifier needs this type of operational amplifier.
quam ut amplificator est:
This is quam ut amplificator est. This is a 4-transistor amplifier circuit diagram. This circuit diagram can make 300 watts using 60-0-60 voltage, 5 amperes. can use 25-0-25 voltage to 60-0-60 voltage. Any NPN and PNP transistors can be used in this circuit diagram. here use 2sc5200 and 2sa1943 transistor.
