#Icircuit op amp 8 pins tv#
It is also used in TV sound systems, AM-FM radio, small servo drivers, and power converters. Used in line drivers, teaching machine outputs, alarms, ultrasonic drivers, It is widely used in simple phonograph amplifiers, intercoms. The abbreviation LM358 indicates an 8-pin integrated circuit, comprising two operational amplifiers at low power. Applications of LM380 Audio Power Amplifier IC: This is how the phase shift oscillator circuit works. And together they make a complete 180° phase shift. Each RC element produces a phase shift of my 60°. An RC network of three resistors and capacitors is connected in the feedback path. LM380 is used to produce a phase shift of 180° in the circuit. This circuit can produce a Sine wave of a desired low to medium frequency. The two input terminals of the speaker are connected to the output of the LM380 IC.Ī phase shift oscillator circuit is as shown in the figure. Here the speaker is not connected to the ground. You can construct a bridge amplifier circuit using two LM380 Audio Power Amplifier ICs. It can drive 4Ω to 8Ω speakers with a good base. This circuit can give an output power of about 3 to 5 watts. The first pin is not connected, pin 2 is non-inverting terminal, pin 3 is inverting input terminal, pin 4,5 is ground, 6 is output, 7 is supply pin and pin 8 is bypass pin. Here all the pins are utilized and IC is very compact. Also, the not connected pins are reduced to one. In this 8 pin IC, all the ground pins are made common. For each circuit, determine the expected gain (Ay). In 14 pin ic, the pin labels are as follows.ġ Bypass, 2 Non-inverting input terminal, 3,4,5,7,10,11 and 12 are the ground pins, pin 8 is an output pin, 14 is the supply, pin 9 and 13 are not connected. The 741 is an 8-pin chip, and the pin numbers are as shown in the diagram.
LM380 IC is available in a 14 pin and 8 pin DIP package.
