CPR135A is an IC specifically designed for reading a certain type of sensor. It is compatible with various types of sensors, such as those detecting infrared and ultraviolet rays. The main purpose of the ROIC is to accumulate photocharges at each pixel and then transmit the resulting signal to the output tab for readout. Traditional ROIC technology involves storing the signal charge at each pixel and routing the signal to the output tab for readout. This requires maintaining a high signal-to-noise ratio (or dynamic range) when storing and reading the signal at each pixel location.
