LM124 LM224 LM324 LM2902
Low Power Quad Operational Amplifiers
General Description

Advantages

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 supplycurrent 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 a 5V power supply voltage which is
used in digital systems and willeasily provide the required
interface electronics without requiring the additional g 15V
power supplies

In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground even though operated from only a single power supply voltage
The unity gain crossfrequency is temperature
compensated
The input bias current is also temperature
compensated

Eliminates need for dual supplies
Four internally compensated op amps in a single
package
Allows directly sensing near GND and VOUT also goes
to GND
Compatible with all forms of logic
Power drain suitable for battery operation
