description  
These devices consist of four independent  
high-gain frequency-compensated operational  
amplifiersthataredesignedspecificallytooperate  
fromasinglesupplyoverawiderangeofvoltages.  
Operation from split supplies is also possible  
when the difference between the two supplies is  
3 V to 30 V (for the LM2902 and LM2902Q, 3 V to  
NC – No internal connection  
symbol (each amplifier)  
26 V) and V  
is at least 1.5 V more positive than

the input common-mode voltage. The low supply  
current drain is independent of the magnitude of  
the supply voltage.

Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational  
amplifier circuits that now can be more easily implemented in single-supply-voltage systems. For example, the  
LM124 can be operated directly from the standard 5-V supply that is used in digital systems and easily provides  
the required interface electronics without requiring additional ±15-V supplies.  
The LM2902Q is manufactured to demanding automotive requirements.  
The LM124 and LM124A are characterized for operation over the full military temperature range of 55°C to  
125°C. The LM224 and LM224A are characterized for operation from 25°C to 85°C. The LM324 and LM324A  
are characterized for operation from 0°C to 70°C. The LM2902 and LM2902Q are characterized for operation  
from 40°C to 125°C.
