Transimpedance Amplifier Circuit

Overview
The transimpedance op amp circuit configuration converts an input current source into an output voltage. The current to voltage gain is based on the feedback resistance. The circuit is able to maintain a constant voltage bias across the input source as the input current changes which benefits many sensors.
Features
- Uses a JFET or CMOS input op amp with low bias current to reduce DC errors
- A bias voltage can be added to the non-inverting input to set the output
- Operates within the linear output voltage swing (see Aol specification) to minimize non-linearity errors
