The LM is a 2. In order to hold system costs to a minimum, the gain is internally fixed at 34 dB. The output of LM is short circuit proof with internal thermal limiting. Equivalent for LM LM The LM is a low power audio amplifier used especially for power audio amplification purposes. This IC can easily drive an 8-ohm speaker with a variable gain of 20 to The IC. So, if you are looking for an audio amplifier IC which can be powered using a battery for a portable application to drive an 8-ohm speaker then this IC might be the right choice for you.
The LM only requires a couple of capacitors and resistors to start working. A very basic commonly used circuit for LM is shown below. The IC is powered using the pin 14 and the ground pin 4 is connected to the ground. The inverting pin is normally grounded and the Non-inverting pin is provided with the audio signal. This audio signal can be from a microphone or even from a 3. The 10k resistor is added in series with the audio signal to act as a volume control.
You can ignore this potentiometer if you want to operate in full volume. This IC comes with a fixed voltage gain of 50dB.

Bypass pin is used for connecting a decoupling capacitor. The Non-Inverting pin is provided with the audio signal.
The Inverting Pin of an amplifier is normally grounded.
2.5W Audio Power Amplifier
The is a power audio amplifier for consumer applications. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output automatically self-centers to one-half the supply voltage.
