Hi Expert,
my customer designed a TIA application using OPA858, DC gain is 30K, AC gain is 100K, when PD received a light, there is no AC signal in output. could you help to give some advice?

Hello Chi,
What are the characteristics of the photodiode (rise time, capacitance, and current range)?
Thank you,
Sima
