Single, Dual, and Quad Micropower, Low Drift, RRIO  
Operational Amplifiers  
ISL28130, ISL28230, ISL28430  
Features  
The ISL28130, ISL28230 and ISL28430 are single, dual and  
quad micropower, low offset drift operational amplifiers that are  
optimized for single and dual supply operation from 1.8V to 5.5V  
and ±0.9V to ±2.75V. Their low supply current of 20µA and  
rail-to-rail input/output enable the ISL28130, ISL28230, and  
ISL28430 to be an excellent general-purpose op amp for a range  
of applications. The ISL28130, ISL28230 and ISL28430 are  
ideal for handheld devices that operate off 2 AA or single Li-ion  
batteries.

The ISL28130 is available in industry standard pinouts for  
5 Ld SOT-23, 5 Ld SC70 and 8 Ld SOIC packages. The ISL28230  
is available in industry standard pinouts for 8 Ld MSOP,  
8 Ld SOIC and 8 Ld DFN packages. The ISL28430 is available in  
14 Ld TSSOP and 14 Ld SOIC packages. Commercial devices  
operate over the temperature range of 0°C to 70°C. Full  
temperature range devices operate over the temperature range  
of -40°C to 125°C.
