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. …
Part Number: LMH34400 Is it OK for LMH3440 as a TIA to convert small current of photo diode to voltage?
The output of LMH3440 is 1Vp-p, would you please suggesst me what kind of OPA is suitable to output 2V for this photo diode detection application

- 16 ch TIAs : LMH34400 - two ports at VDD = 3.3V, IDC_EN =…
Hi Robert,
Thanks for the further feedback. For smaller sized COG style ceramic capacitors, they actually hold up fairly well across frequency which is why we suggest them in parallel with the larger caps. Below is an image from an AVX document where…
