DATASHEET ISL28134 5V Ultra Low Noise, Auto-Zero Rail-to-Rail Precision Op Amp FN6957 Rev.6.03 Oct 27, 2022 The ISL28134 is a single, auto-zeroing 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-zeroing 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.
