It is a flexible device the frequency response can be shaped with some external components and there are plenty. This design (from the mid 70’s) has been always a popular choice for low-powered audio applications.

if it works and i like it i'll add the oscillation thingy. The LM386 is a Voltage Audio Power Amplifier manufactured by National Semiconductor and JRC/NJM. teh oscillation part as well leaving it quite naked. is it like a dying battery sim?) and the output vol and tone. im thinking of eliminating some stuff like the gate and starve pot (i dont get what it does tho. If a capacitor is put from pin 1 to 8, bypassing the 1.35-k resistor, the gain will go up to 200 (46 dB).

With pins 1 and 8 open the 1.35-k resistor sets the gain at 20 (26 dB). The LM386 is fine for driving inexpensive headphones, but noise and distortion figures pale in comparison to what can be achieved with either a well-designed discrete component amplifier or as with this project a ‘precision’ headphone driver IC. It costs less than 3 in partsSponsored by The Great. Datasheet says: To make the LM386 a more versatile amplifier, two pins (1 and 8) are provided for gain control. are the y different or is it quite the same?Īnd the drive pots lugs are like 1-not connected, 2-coming from the R6 and 3-ground? i dont see how it would work (sorry if this is a stupid question here)Īnd if i get it correctly the R10 R11 C5 C6 C8 are just for the mid lift meaning these can be eliminated?Īnd i've already read some stuff about it. How to use the popular LM386 class AB audio amplifier IC to build a simple mono 1 watt audio amplifier. found a few schemes or something but can't quite figure it out any PCB layouts? Tho teh reason iwas asking is cz i built grace and it didnt work for some reasonĪs for the Hotcake. After doing so i decided to make the other channel stereo sound and replicated the circuit on the other side of the board. Ahh yeah i got it actually from Germany to substitute j201 This headphone amplifier circuit is made by using lm386 audio amplifier ic.
