Hi, I am wondering for which applications we use OpAmp with high output current ? Normally, if we have a current pulse as sensor output we need to use transimpedance amplifier to convert the current pulse to voltage signal and then ADC sample it to process digitally with FPGA but how about the output current capability of an OpAmp where we need to consider it and for which applications it matters. I also notice that OpAmp with high output current have low bandwidth.
