Electronics Help Care Amplifier circuit diagram
Mini audio amplifier circuit diagram. This circuit runs using 5 voltage to 12-volt supply. It’s a mono amplifier circuit diagram. It’s a mini amplifier circuit board. here use one IC and one capacitor only. LM 386N and 220mfd 25 volt capacitor.
LM386 is a popular IC. A low-voltage power amplifier IC designed for a battery. low-power applications like guitar amps, small radios, and DIY electronics. It operates between 4 and 18 volts. The adjustable gain drives 4-8 Ohm speakers.
Operating Voltage is: 4Volts to 18V (depending on diagram). Output watts is typically 0.25W to 2Watts. Internally set is 20, adjustable from 20 to 200 using a resistor and capacitor between pins 1 and 8.
low pass filter for subwoofer amplifier:
This is the low-pass filter for the subwoofer amplifier. This circuit needs to make a bass amplifier. We also need to make a 2.1,5.1 audio sound system. This board makes only bass. makes only the low part. It has no mid-range or high part. It’s also a pre-amplifier. It’s output mono. Input stereo but output mono. This board runs on 9 volts to 15 volts. It needs a single voltage. For this, we can use this board in the car amplifier.
This board is designed with 4558D. We can also use the NE5532 IC. It has 2 volumes to control the sound. One is the master volume, the one is the frequency volume. The voltage requirement is 12 volts and 2 amperes.
