Other Parts Discussed in Thread: OPA4820, LMH32401, TLV3544
Tool/software:
If using photodiodes as current sources, would the simplest way to AC-couple for ambient light filtering be via in-series capacitors prior to the input pin? What would the tradeoffs be to implement this versus setting up another power line to connect the PDs with a negative reverse voltage to make use of the integrated ambient light filtering of the LMH32404?
Thank you!
