The LM124-N series consists of four independent high-gain internal frequency-compensated operational amplifiers designed to operate from a single power supply over a wide voltage range. It is also possible to operate from a split supply, where the loss of low supply current is independent of the magnitude of the supply voltage.
Function block diagram
Applications include transducer amplifiers, DC gain blocks and all conventional op-amp circuits that can now be more easily implemented in a single power supply system. For example, the LM124-N series can operate directly at the standard 5-V power supply voltage used in digital systems, easily providing the required interface electronics without the need for an additional ±15 V power supply.
