The LM324-N consists of four independent, high-gain, internally frequency-compensated operational amplifiers. These amplifiers were designed specifically to operate from a single power supply over a wide voltage range. Operation from split-power supplies is also possible. The low-power supply current drain is independent of the supply voltage magnitude. Application areas include transducer amplifiers, DC gain blocks, and conventional op-amp circuits, easily implemented in single power supply systems.
The input common-mode voltage range includes ground, allowing direct sensing near ground. The output can swing to ground even when operated from a single power supply. Unity gain cross frequency and input bias current are temperature compensated.
