LM324 四运算放大器 (Low Power Quad O

LM324 四运算放大器：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. 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.
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.
