Bog'liq elektronika5.Operatsion Kuchaytirgichlarni Moslashish.
LM324 mikrosxemasi bitta to'plamda yig'ilgan to'rtta bir xil operatsion kuchaytirgichdan (op-amp) iborat bo'lib, keng kuchlanish diapazonida bitta quvvat manbaidan ishlaydi. Har bir opamp kirish differensial bosqichini, qisqa tutashuvdan himoya qilishni va birlik daromadida ichki chastotani tuzatishni o'z ichiga oladi.
Ushbu qurilmaning xarakteristikalari va arzonligi uning havaskor radio sxemalari va sanoat elektronikasida keng qo'llanilishini ta'minlaydi. Bu ixcham, portativ elektron qurilmalarda foydalanish uchun ideal.
U DIP tipidagi paketlarda ishlab chiqariladi: plastmassa CDIP, keramik PDIP yoki sirtni o'rnatish uchun SO-tipi: SOIC, TSSOP. Strukturaviy tarzda, qurilma 14 ta pinga ega. Shuning uchun, ba'zilarida texnik tavsiflar, DIP-14 yoki SO-14 belgisi topilgan.
Turli holatlar uchun pinlarning tayinlanishi bir xil: 2,3, 5,6, 9,10, 13,12 - kirishlar, 1,7,8,14 - chiqish, 4 - ortiqcha quvvat manbai, 11 - minus quvvat manbai.
