5V Ultra Low Noise, Zero Drift Rail-to-Rail Precision

Op Amp

ISL28134

Features

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.
