5V Ultra Low Noise, Zero Drift Rail-to-Rail Precision  
Op Amp  
ISL28134  
Features  
The ISL28134 is a single, chopper-stabilized zero drift  
operational amplifier optimized for single and dual supply  
operation from 2.25V to 6.0V and ±1.125V and ±3.0V. The  
ISL28134 uses auto-correction circuitry to provide very low input  
offset voltage, drift and a reduction of the 1/f noise corner below  
0.1Hz. The ISL28134 achieves ultra low offset voltage, offset  
temperature drift, wide gain bandwidth and rail-to-rail  
input/output swing while minimizing power consumption.

The ISL28134 is ideal for amplifying the sensor signals of analog  
front-ends that include pressure, temperature, medical, strain  
gauge and inertial sensors down to the µV levels.  
The ISL28134 can be used over standard amplifiers with high  
stability across the industrial temperature range of -40°C to  
+85°C and the full industrial temperature range of -40°C to  
+125°C. The ISL28134 is available in an industry standard  
pinout SOIC and SOT-23 packages.
