LM324M 参数 Datasheet PDF下载

Quadruple Operational Amplifiers

DESCRIPTION

The LM324 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.

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.
