![]() The peak-to-peak voltage calculator finds the peak-to-peak voltage, $$V_$$: The level of a waveform defined by the condition that the area enclosed by the curve above this level is exactly equal to the area enclosed by the curve below this level. The gain of this amplifier is 20.Using the Peak-to-Peak Voltage Calculator This network also called the “Zobel network” and it is used to remove the oscillations or noise due to sudden high frequencies. A network of 0.05♟ filter capacitor and 10k resistor is used at the pin 5. It removes DC offset from the output if any and allows only AC signal to pass through it. A 250♟ coupling capacitor is connected to the output pin. The potentiometer acts as a knob for controlling volume. Here pin 2 is grounded and pin 3 is connected to a potentiometer of 10kΩ. The signals to be amplified are applied at pins 2 and 3. It is basically designed for low voltage applications. It can be used in FM radio amplification, intercoms, line and servo drivers, TV sound systems, power converters etc. LM386 IC is ideal for 6V battery operation applications. By adding a resistor in series with the capacitor the gain can be modified pertaining to the requirement. By connecting a capacitor between Pins 1 and 8, the 1.35 K internal resistor is bypassed and the gain is set at 200 (46dB). The first two voltage models have a voltage range of 4V to 12V while LM386N-4 has a voltage range of 5V to 18V. The primary operation of LM386 is the gain control provided by Pins 1 and 8. This LM386 is available in three different models in the market which include LM386N-1, LM386N-3 and LM386N-4. Where to Use Low Voltage Audio Amplifier? The harmonic distortion is less than 0.2%.It has a self-centering output voltage which automatically biases to one-half the supply voltage.The inputs are referenced by the ground.It is from 4volts to 12volts or 5volts to 18 volts depending on the model. The range of voltage supply depends on the model used.The voltage gain range of this amplifier is from 20 to 200.LM386 Low Voltage Audio Power Amplifier Features ![]()
