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.
