DESCRIPTION
The LM124/124A 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 LM124/124A
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 Rrange 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
Advantages
• Eliminates Need for Dual Supplies
• Four Internally Compensated Op Amps in a Single Package
• Allows Directly Sensing near GND and V_OUT also Goes to GND
• Compatible with all Forms of Logic
• Power Drain Suitable for Battery Operation
