| Abstract: |
| LM324 is a four-integration operation amplifier. Due to its low cost and easy to use, it is widely used in control and magnification of general signals.By careful design and repeated test, magnification of precise instrumental signals is achieved by using the circuit composed of LM324. Its main technical specifications such as stability, linearity, magnification and stability of temperature are similar to that of precise amplifiers. |
