Dual and Quad Micropower Chopper Stabilized, RRIO  
Operational Amplifiers  
ISL28233, ISL28433  
Features  
The ISL28233 and ISL28433 are dual and quad micropower,  
chopper stabilized operational amplifiers that are optimized for  
single and dual supply operation from 1.8V to 6.0V and ±0.825V  
to ±3.0V. Their low supply current of 18µA and wide input range  
enable the ISL28233, ISL28433 to be excellent general purpose  
op amps for a wide range of applications. The ISL28233 and  
ISL28433 are ideal for handheld devices that operate off 2 AA or  
single Li-ion batteries.
