The TC285SPD is a 1004x1002 30-Frame/s readout, frame-transfer CCD image sensor designed for use in black and white, bio-medical, and special-purpose applications requiring high sensitivity, high speed, high resolution, and low noise. The TC285SPD is a new device of the IMPACTRONTM family of very-low noise, high sensitivity, high-speed, and high-resolution image sensors that multiply charge directly in the charge domain before conversion to voltage. The charge carrier multiplication (CCM) is achieved by using a low-noise single-carrier, impact ionization process that occurs during repeated carrier transfers through high field regions.
