1 / 20 page 1 5V Ultra Low Noise, Zero Drift Rail-to-Rail Precision Op Amp ISL28134 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 features very low input offset voltage and low noise with no 1/f noise corner down to 0.1Hz. The ISL28134 is designed to have ultra low offset voltage and offset temperature drift, wide gain bandwidth and rail-to-rail input/output swing while minimizing power consumption. This amplifier is ideal for amplifying the sensor signals of analog front-ends that include pressure, temperature, medical, strain gauge and inertial sensors. The ISL28134 can be used over standard amplifiers with high stability over the industrial temperature range of -40°C to +85°C. The ISL28134 is available in an industry standard pinout SOIC package.
