Hello friends,
I have connected the circuit as per Figure 6 - (a) page:12, in OPA380 datasheet(http://www.ti.com/lit/ds/symlink/opa380.pdf). It is working well and good. But i have reversed the photodiode (kept in Forward bias) with 5V at the cathode of photodiode. Now the photodiode is giving positive pulses, but opa380 output is not inverted.
If negative pulses are given to inverting pin positive pulses of amplified signals are obtained. Similarly if i give the positive pulses i can get the negative pulses of amplified signals.
Is there any circuit still need to modify. or this will not work?
Please reply me
