JAJSQO6 august 2023 LOG200
ADVANCE INFORMATION
A common use case for the LOG200 is an optical current sense circuit, using an external photodiode. Figure 8-5 shows an implementation using an InGaAs, PIN photodiode for a λ = 1.31‑μm application. This design uses ±5‑V supplies and is intended for use with input currents from 10 nA to 100 µA. Decoupling capacitors are not shown for brevity. The design can be easily implemented using the LOG200 Evaluation Module board.
