Lab 4 – Audio Amplifiers Part A: Audio Amps 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? Features Battery Operation Minimum External Parts Wide Supply VoltageRange:4 V–12 V or 5 V–18V Low QuiescentCurrentDrain:4 mA Voltage Gains from 20 to 200 Ground-Referenced Input Self-Centering Output Quiescent Voltage Low Distortion:0.2%(AV= 20, VS= 6 V, RL= 8Ω,PO= 125 mW,f = 1 kHz) Available in 8-Pin MSOP Package Applications: AM-FM Radio Amplifiers Portable Tape Player Amplifiers Intercoms TV Sound Systems Line Drivers Ultrasonic Drivers Small Servo Drivers Power Converters
