Amplifier circuit using MOSFET K1058 and J162:
This is the amplifier circuit using MOSFET K1058 and J162. This circuit can produce 100 watts at a 35-0-35 voltage. This is a mono diagram. For stereo, it needs dual circuits. We can also use another MOSFET.
Type Designator is 2SK1058. The type of Transistor is MOSFET. The type of Control Channel is N-channel. The Maximum Power Dissipation is 100 W. The maximum Drain-Source Voltage is 160 V. The maximum Gate-Source Voltage is 15 V. The minimum Gate-to-Source Cutoff Voltage is 0.15 V. The maximum Drain Current is 7 A.
Type Designator is 2SJ160. The type of Transistor is MOSFET. The type of Control Channel is P-channel. The Maximum Power Dissipation is 100 W. The maximum Drain-Source Voltage is 120 V. The maximum Gate-Source Voltage is 15 V. The minimum Gate-to-Source Cutoff Voltage is 0.15 V. The maximum Drain Current is 7 A.
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.
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
The LM3915 is a mono-integrated circuit that has analog voltage levels. It drives ten LEDs and LCDs. providing a logarithmic 3 dB/step analog display. 1 pin changes the display from a bar graph to a moving one. LED current drive is regulated. It’s needed for current limiting resistors. This circuit can operate from a single supply minimum of 3 volts or a maximum of 25 volts. The input buffer accepts signals down to the ground and up to within 1.5 volts of the positive supply; it needs no protection against inputs of ±35 volts. The audio input stupid drives 10 separate comparators referenced. Accuracy’s better than 1 dB. The LM3915’s 3 dB/step display is suited for signals. such as audio level, power, and light intensity. Audio includes average or peak level indicators. Replacing usual meters with an LED bar graph results in a faster response.
The LM3915 is extremely easy to use. A 1.2V full-scale meter demands only one resistor in addition to
the last, which means ten LEDs. LED brightness is easy to control
