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 over 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.
