The LM324N is a general purpose amplifier DIP-14 RoHS manufactured by HGSEMI, which features an internal 14-Pin dual-in-line plastic package. It is designed to operate from a single supply over a wide range of voltages, and it has high phase linearity and stability over temperature and supply variations. This device consists of four independent, high-gain, internally frequency compensated operational amplifiers, which can be used to add, subtract, differentiate and integrate signals. It has low power consumption and a wide common mode and different gain voltage range. The LM324N allows for a slew rate of 13V/µs, a gain bandwidth product of 1MHz, and an input voltage range of 10V to 32V. It also has a typical temperature coefficient of 0.05%/°C and a maximum input bias current of 10nA.
