ISL28134：零漂移軌對(duì)軌放大器概述
英飛凌汽車電子生態(tài)圈
The ISL28134 is a single, chopper-stabilized Zero-Driftoperational amplifier optimized for single and dual supplyoperation from 2.25V to 6.0V and ±1.125V and ±3.0V. TheISL28134 uses auto-correction circuitry to provide very low inputoffset voltage, drift and a reduction of the 1/f noise corner below0.1Hz. The ISL28134 achieves ultra low offset voltage, offsettemperature drift, wide gain bandwidth and rail-to-railinput/output swing while minimizing power consumption.
本文引用地址：http://www.ex-cimer.com/article/258519.htmThe ISL28134 is ideal for amplifying the sensor signals of analogfront-ends that include pressure, temperature, medical, straingauge and inertial sensors down to the μV levels.The ISL28134 can be used over standard amplifiers with highstability over the industrial temperature range of -40°C to +85°Cand the full industrial temperature range of -40°C to +125°C.The ISL28134 is available in an industry standard pinout SOICand SOT-23 packages.
