LM124AQML
LM124QML
Low Power Quad Operational Amplifiers
General Description
The LM124/124A consists of four independent, high gain, in-
ternally 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 LM124/124A can be directly operated off of
the standard +5Vdc power supply voltage which is used in
digital systems and will easily provide the required interface
electronics without requiring the additional +15Vdc power
supplies.

Unique Characteristics
■
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 cross frequency is temperature
compensated
■
The input bias current is also temperature compensated
