The OPA857IRGTT is a wideband fast overdrive recovery fast-settling ultralow-noise Transimpedance Amplifier for use with photodiode monitoring applications. With selectable feedback resistance, the OPA857 simplifies the design of high-performance optical systems. Very fast overload recovery time and internal input protection provide the best combination to protect the remainder of the signal chain from overdrive while minimizing recovery time. The two selectable transimpedance gain configurations allow high dynamic range and flexibility required in today's transimpedance amplifier applications.
