Part A: Audio AmpsTCO #4:Given an audio amplifier application that uses an integrated amplifier, examine the overall amplifier’s performance and verify theoperation by using suitable input and output circuits.Investigation of the LM386 Audio Amplifier takes place during week 4. The LM386 is a versatile special purpose op-amp used to amplifier audio frequencies. The device is contained in a single 8-pin dip package and has a gain of up to 200 and a power output of 1-watt.A.Use an Internet search utility, such as Google, find an audio amplifier suchas a LM386 download the specification sheet and determine its general characteristics such as its general description, the package type and pin configuration.a.Use the Internet to search for a LM386 data sheet. Try or . Print the datasheet.b.From the data sheet find the following information and record.What are its general characteristics?

B.Use the specification sheet to determine its electrical characteristics and operating values.a.Record the electrical values of the LM386. Absolute Maximum Ratings: Supply Voltage >15 Package Dissipation 1.25 Watts Input Voltage +/- 0.4 V Electrical Characteristics: Operating supply voltage -0.4V to 12V Output power 250mW-325mW Voltage gain -6v ---- f=1kHz .25dB Bandwidth 300kHz Input Resistance 50kΩ C. 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.
