LM386N Audio Power Amplifier IC

LM386 low voltage audio power amplifier designed as 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.

The IC LM386 designed as one of the prominent integrated circuit used in the audio section. Also widely used for voice record from microphone, battery operated speakers. The quiescent power drain is only 24mW  when operating from a 6V supply, this makes it ideal for battery operation. The LM386  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. Meanwhile, this device comes in three different 8-pin packages as PDIP, SOIC, and VSSOP to fit in different applications.
