Alternatively, it is much cheaper to buy a readymade module online for 99p and it works far better due to short tracks and SMD components. Jika kedua pin dibiarkan terbuka, gainnya akan sama. Secara singkat fungsi pin dari IC LM386 ini antara lain : Gain : berfungsi untuk pengaturan gain. Gambar IC LM386 SMD dan keterangan pinout nya. Dipasaran LM386 terdapat jenis IC tipe Soic 8 atau Dip 8. Gain penguatan yaitu 10 dari 20 menjadi 200. All the versions are available in dual in-line package (DIP), which is useful for hobby amplifier projects however. Tegangan kerja rangkaian antara 4 12 Vdc. There are three versions of this IC, LM386N-1, LM386N-3, LM386N-4, capable of providing power output of 0.125 W, 0.8 W, and 1 W respectively. If you are constructing this circuit on breadboard, then it is better to keep all the wires short, otherwise, increasing the gain to 200 can introduce feedback noise. The LM386 is a low voltage audio amplifier IC manufactured by National Semiconductor. The main advantage of this IC is its bass boost function with the addition of only two external components. The LM386 is a mono amplifier IC with a default fixed gain of 20, and may be set to 200 (gain = 200) after the addition of a 10 ♟ capacitor between pin 1 and pin 8. All the versions are available in dual in-line package (DIP), which is useful for hobby amplifier projects however, the LM386M-1 version is available in SO package, and the LM386MM-1 version is available in mini small outline package. There are three versions of this IC, LM386N-1, LM386N-3, LM386N-4, capable of providing power output of 0.125 W, 0.8 W, and 1 W respectively. The LM386 is a low voltage audio amplifier IC manufactured by National Semiconductor.
