Hello Zhang,
Thank you for your patience on this issue. I reviewed your question and additional reply, and below is our feedback:
This type of behavior is normal since the laser diode output current/type will differ with different amount of lights received…
Part Number: LMH34400 Other Parts Discussed in Thread: TPS40210 Tool/software: Hi,
We use the LMH34400 in our laser radar project, and we use the TDC design, and now, please kindly avise if LMH34400 can connect to the APD for the gain, thanks.

In above image it is shown schematic and its output waveform, as here i am getting very low Vpp, need to get it around 1Vpp, how to achive it
Hello Youngjoon,
Thank you for sharing this update! I am glad you were able to find a working solution, that is really good to know about R5 (output resistor) affects on the comparator.
Best Regards, Sima
Part Number: LMH34400 Hello team,
My customer would like to sense photo diode (transimpedance circuit) with single supply OPAMP.
However, if the Opamp is operated with single supply, it will require bias voltage because if the photo current = 0A, then…

Part Number: LMH34400 Other Parts Discussed in Thread: LMH6611 , Hi TI,
Just get the LMH34400 + LMH6611 PCBA from menufactory, somes questions as below
1. Is it normal for LMH34400 always outputs 0.3V even there is no input
2. Is R25 = 49.9R OK for LMH6611…
Part Number: LMH34400 Hi
I want to know that the TIA "LMH34400" can be used for balanced photo-detection.
Is it possible to use it in this application?
if possible, I would like to amplify the signals coming from a balanced photo-detector. …
