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 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 V levels.
The ISL28134 can be used over standard amplifiers with high
stability over 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.
Applications
Medical instrumentation
Sensor gain amps
