Input Resistance50kohmsC.Using information from the data sheet or other sources and an application such as Multisim, Visio, or a CAD program draw the schematic and verify the component values of an audio amplifier application using the device.a.Using the Typical Applications section or other source find an amplifier with a gain equal to 20. b.Use an application such as Multisim, Visio, or a CAD program to create the circuit schematic. Label the schematic, LM386 Audio Amplifier. c.Label the pin numbers on the LM386 and give each component a name and value. d.Explain briefly how the gain of the LM386 can be changed. D.Construct the audio amplifier on your breadboard with various gains (20 and 200). Using a frequency generator as an input, verify the amplification of the audio amplifier. Use 10mV peak as the input signal
a.For measurements purposes, prototype an amplifier similar to the one below. Remember keep all component connecting wires as short as possible, and keep all components as close to the audio amplifier as possible. The 10mV peak input is set between the 1k resistor and C6.b.Complete the table below. R C 5 ( ) in pp V ( ) out pp V Expected Measured Gain Gain 1kΩ 10uF 10mVp 8mVp .8 1.2 k 10 F 10mVp 8mVp .8 _____ 1.5kΩ 10 F 10mVp 8mVp .8 _____
c.Beginning with pin 1 an 8 open and the frequency generator set to 10 mVp at 1 kHz, use the oscilloscope to measure the voltage values. Calculate the gain of the amplifier, outVinvAv. Record the results on the sheet. d.Continue this procedure until you have determined the three gain values.e.Were there any problems with the different gain values? If so, explain the symptoms and how to correct the problem.
