DESCRIPTION
The LM124-N 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-N
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.

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
