ISL28134 FN6957
Rev 6.00
October 14, 2014 5V Ultra Low Noise, Zero Drift Rail-to-Rail Precision Op Amp
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 В±1.125V and В±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 railto-rail input/output swing while minimizing power
consumption. Features 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 ВµV levels. Low offset voltage 2.5ВµV, Max The ISL28134 can be used over standard amplifiers with high
stability across the industrial temperature range of -40В°C to
+85В°C and the full industrial temperature range of -40В°C to
+125В°C. The ISL28134 is available in an industry standard
pinout SOIC and SOT-23 packages. Rail-to-rail inputs and outputs
