Photovoltaic Transimpedance Amplifier Circuit Diagram

Photovoltaic
The following schematic shows the Photovoltaic Transimpedance Amplifier Circuit Diagram. This design combines two Intersil X9258T digitally controlled potentiometers with an AD822 low noise dual op amp to create a flexible, digitally calibrated, wide dynamic range transimpedance amplifier topology that can be used with virtually any photovoltaic detector technology. The amplifier output is given by:

Vo = Is(1MΩ) ((1+P1)/(256-P1))

Where P1 is the 8-bit (0 to 255) digital value written to DCP1. For more detail information on Photovoltaic Transimpedance Amplifier Circuit Diagram, download the following file.
