Typical Single-Supply Applications — (V

+ = 5.0 V

DC)

Figure 35. Photodiode Current-to-Voltage Converter

Note: A 5V bias on the photodiode can cut its capacitance by a factor of 2 or 3, leading to improved response and

lower noise. However, this bias on the photodiode will cause photodiode leakage (also known as its dark current).

Figure 36. Micropower Current Source

Note: (Upper limit of output range dictated by input common-mode range; lower limit dictated by minimum current

requirement of LM385.)
