Reference Design for Extending the OPA857 Transimpedance Bandwidth

Description

The OPA857 is a wideband, ultralow noise transimpedance amplifier (TIA) targeted at photodiode monitoring applications. The OPA857 has two selectable gain configurations of 5kΩ and 20kΩ while maintaining a nearly constant closed-loop bandwidth in excess of 100MHz . In this reference desi

Features
  • Extending the bandwidth of the OPA857 from 100MHz to greater than 250MHz Adjusting the gain of the OPA857 between 1-20kΩ Evaluation module allows flexibility in testing the OPA857 in internal test mode or with an exte
