Ground pin connected to the ground terminal It is the inverter pin and has a connection to ground Pin noĪdjust the gain of the amp by connecting IC to an external capacitor The LM386 has an 8-pin configuration and is as depicted below. Wide voltage gain range of 20 to 200(26dB to 46dB).The LM386 IC bears some unique traits, as discussed below. ( an up-close photo of an LM386 IC) IC LM 386: Characteristics of the LM386 This adjustment makes it possible to control the volume from an external audio source accordingly. Interestingly, the voltage default gain usually is adjustable to 20, but you can also amplify this gain to 200 by having external resistors and capacitors co-joining the IC. The LM386 IC comes with an 8-pin configuration whereby it has two gains, ground, Vout, Bypass, among others. It uses a low power supply from batteries or a common DC input type of electricity. What is IC LM386?Īs stated earlier, the LM386 is an IC that works as an amplifier. By the time we complete the piece, we will fully comprehend the workings of the LM386. So, the purpose of this article would be to familiarize ourselves with the ins and outs of the LM386. It draws power from low voltage sources like batteries, for instance, to power the audio devices. You might have consciously or unconsciously come across the IC LM 386 amplifier for audio enthusiasts.
