The silk-screen 321 is a kind of CMOS operational amplifier, model SGM321. Its parameters are operating frequency of 1MHz, maximum operating current of 60A, Vs = 5.5V, VCM = -0.1V to 4V, RL = 5K? Vo = 0.1V to 4.9V. CMOS refers to a technology used in the manufacture of large-scale integrated circuit chips, or chips made with this technology, which is a read-write RAM chip on a computer motherboard. Because of the read-write characteristics, it is used to save the data after the BIOS is set up on the computer hardware parameters on the computer motherboard, and this chip is only used to store data.
