National Semiconductor LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers Datasheet
The LM124 series consists of four independent, high gain, internally frequency compensated operational amplifiers designed to operate from a single power supply over a wide range of voltages. These devices are suitable for application areas including transducer amplifiers, DC gain blocks, and conventional op amp circuits in single power supply systems.
