FEATURES  
ADVANTAGES

Internally Frequency Compensated for Unity  
Gain  
Eliminates Need for Dual Supplies  
Four Internally Compensated Op Amps in a  
Single Package  
Large DC Voltage Gain 100 dB  
Wide Bandwidth (Unity Gain) 1 MHz  
(Temperature Compensated)  
Allows Directly Sensing Near GND and VOUT  
also Goes to GND  
Wide Power Supply Range:  
Compatible with All Forms of Logic  
Single Supply 3V to 32V  
Power Drain Suitable for Battery Operation  
or Dual Supplies ±1.5V to ±16V  
DESCRIPTION  
Very Low Supply Current Drain (700  
μA)—Essentially Independent of Supply  
Voltage  
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.  
Low Input Biasing Current 45 nA (Temperature  
Compensated)  
Low Input Offset Voltage 2 mV  
and Offset Current: 5 nA  
Input Common-Mode Voltage Range Includes  
Ground  
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.  
Differential Input Voltage Range Equal to the  
Power Supply Voltage  
Large Output Voltage Swing 0V to V+ 1.5V  
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
