position as close to the input terminal as possible.

Driver circuit consideration
The following points must be taken into account when you use a driver circuit.
The input pulse must meet the pulse conditions at the input terminal. Each pulse should be amplified by the buffer at a
The video output should undergo non-inverting amplification at the external readout circuit.
Use of a JFET input type op amp is recommended. Make offset adjustment as necessary. In this case, it should be
noted that the dark output level appears on the lower voltage side relative to the output offset voltage.
