National Semiconductor LM324
The LM124 series consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. For example, the LM124 series can be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ± 15V power supplies.GENERAL DESCRIPTION
Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. Advantages n Eliminates need for dual supplies n Four internally compensated op amps in a single package n Allows directly sensing near GND and VOUT also goes to GND n Compatible with all forms of logic n Power drain suitable for battery operationFEATURES
