Part Number: OPA855 Other Parts Discussed in Thread: OPA858 , When working on a 1000M bandwidth amplifier circuit, I need to perform IBIS simulation. How can I obtain the IBIS models for the OPA855 and OPA858 chips? Can E2E technical support respond with…
Hi YINGBO,
We typically do not recommend using a current feedback amplifier in a TIA application for a couple reasons. The first reason being that compensating the circuit becomes more difficult than when using a voltage feedback device. There are also…

Part Number: OPA657 Other Parts Discussed in Thread: TINA-TI , OPA818 , OPA855 , OPA858 您好! 我用一个LED和PD、以及OPA657搭了一个测试光电流的链路,如图
LED连接AWG给正弦波信号,然后PD接收,经过TIA放大后连接示波器看波形。OPA657电路设计原理图和PCB如下
PCB中,信号线下面的电源和地平面都挖空了,在实际测试中,我并没有焊接反馈电容。
由于我不知道测试中光电流的大小,我测试了AWG发出10Khz和1Mhz情况下的波形幅值做对比…
