ABSTRACT:
A transimpedance amplifier according to an exemplary aspect of the present invention includes a first terminal supplied with a first power supply voltage, and a second terminal supplied with a second power supply voltage having a potential lower than that of the first power supply voltage. The transimpedance amplifier outputs a voltage signal that is converted into a binary signal of one of the first power supply voltage and the second power supply voltage, based on an input analog current signal. This makes it possible to reduce a conversion error.
