40V Precision Single Supply Rail-to-Rail Output  
Low Power Operational Amplifiers  
ISL28118, ISL28218  
Features  
• Rail-to-Rail Output  
The ISL28118 and ISL28218 are single and dual  
precision, single supply rail-to-rail output amplifiers with  
a common mode input voltage range extending to 0.5V  
below the V- rail. These op amps feature low power, low  
offset voltage, and low temperature drift, making them  
the ideal choice for applications requiring both high DC  
accuracy and AC performance. The devices can operate  
from single (3V to 40V) or dual (±1.5V to ±20V)  
supplies. The combination of precision and small  
footprint provides the user with outstanding value and  
flexibility relative to similar competitive parts.
