LM380N Audio Power Amplifier IC

LM380 designed as a power audio amplifier ideal in the consumer application.  This module operates at a voltage range between 10V and 22V. This module can generate a dissipating power rate of 0.75w. gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output is short circuit proof with internal thermal self-centers to one-half the supply voltage limiting. Moreover, the LM380 chips are available as  standard dual-in-line. The LM380N uses a copper lead frame. The center three pins on either side comprise a heat sink. Thus makes the device easy to use in standard PC layouts

The IC LM380 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 0.13mW  when operating from a 10V supply, this makes it ideal for battery operation. The LM386  audio power 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.
