9.2.2 Single-Supply Photodiode Amplifier

Photodiodes are used in many applications to convert light signals to electrical signals. The current through

the photodiode is proportional to the photon energy absorbed, and is commonly in the range of a few hundred

picoamps to a few tens of microamps. An amplifier in a transimpedance configuration is typically used to convert

the low-level photodiode current to a voltage signal for processing in an MCU. The circuit shown in Figure 9-3 is

an example of a single-supply photodiode amplifier circuit using the TLV9002.
