LM124/LM224/LM324/LM2902  
Low Power Quad Operational Amplifiers  
General Description  
Advantages  
n Eliminates need for dual supplies  
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 sup-  
ply current drain is independent of the magnitude of the  
power supply voltage.  
n Four internally compensated op amps in a single  
package  
n Allows directly sensing near GND and VOUT also goes  
to GND  
n Compatible with all forms of logic  
n Power drain suitable for battery operation  
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 sys-  
tems. For example, the LM124 series can be directly oper-  
ated off of the standard +5V power supply voltage which is  
used in digital systems and will easily provide the required  
Features  
n Internally frequency compensated for unity gain  
n Large DC voltage gain 100 dB  
n Wide bandwidth (unity gain) 1 MHz  
(temperature compensated)  
±
interface electronics without requiring the additional 15V  
power supplies.  
n Wide power supply range:  
Single supply 3V to 32V  
±
±
1.5V to 16V  
or dual supplies  
Unique Characteristics  
n Very low supply current drain (700 µA)essentially  
independent of supply voltage  
n Low input biasing current 45 nA  
(temperature compensated)  
n Low input offset voltage 2 mV  
and offset current: 5 nA  
n 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  
n The unity gain cross frequency is temperature  
compensated  
n Input common-mode voltage range includes ground  
n Differential input voltage range equal to the power  
supply voltage  
n Large output voltage swing 0V to V+ − 1.5V  
n The input bias current is also temperature compensated
