The ISL28107, ISL28207 and ISL28407 are single, dual and  
Features  
quad amplifiers featuring low noise, low input bias current,  
and low offset and temperature drift. This makes them the  
ideal choice for applications requiring both high DC accuracy  
and AC performance. The combination of precision, low noise,  
and small footprint provides the user with outstanding value  
and flexibility relative to similar competitive parts.
