Renesas Electronics ISL28134 Rail-to-Rail Op Amp
Renesas Electronics ISL28134 Ultra-Low Noise, Zero Drift Rail-to-Rail Op Amps are a single, chopper-stabilized Zero-Drift operational amplifier that is 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.
