Transimpedance amplifiers (TIAs) act as front-end amplifiers for optical sensors such as photodiodes, converting the sensor’s output current to a voltage. TIAs are conceptually simple: a feedback resistor (RF) across an operational amplifier (op amp)…

In my previous blog on "How to evaluate a transimpedance amplifier, part 1", we looked at the OPA857 performance, but didn’t go in depth in explaining how those measurements were taken.  Now that we’ve have established a reference, let’s work th…

In this blog, I want take a different approach and describe the technical challenge encountered while bench characterizing the OPA857, a dedicatedtransimpedance amplifier (TIA) with two internal gain settings operating on a +3.3 V supply supporting a…
