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.
