Description
LM386 low voltage audio power amplifier is a mono audio amplifier ideal in the application which requires a small amplifier. LM386 chips are available as SO packages manufactured by TEXAS instruments. This module operates at a voltage range between 4V and 12V and has a maximum rating of 15v. This module can generate a dissipating power rate of 0.75w. LM386 low voltage audio power amplifier can provide a typical output of 325mW, under the condition supply voltage is 6v and the speaker load is 8ohm. An output power 500W generated for a 9V supply, as a result, it is a highly reliable and low-cost audio signaling device.
Power LED provided to indicate any troubleshooting. If the LED does not light up indicate the proper working of the circuit. LM386 audio amplifier IC also provides better signal gain, when a capacitor is connected between pin 1& 8. If there is no connection between these pins, the default gain will be 26db. Unnecessary oscillations avoided by the filtering capacitor in pin7.
The quiescent power drain is only 24mWÂ when operating from a 6V supply, this makes it ideal for battery operation. The LM386Â mono low voltage amplifier used in a variety of applications. It drives loads from 4ohm to 32ohm. The gain internally set as 20 and modifies from 20 to 200 using a resistor and a capacitor placed between pins 1 and 8. This device comes in three different 8-pin packages as PDIP, SOIC, and VSSOP to fit in different applications.
