Note 3: Measured at 50% of SE (Typ.) Definition of PRNU: PRNU = Dc c 100% Where ? is average of total signal outputs and ,? is the maximum deviation from ? under uniform illumination. Note 4: VSAT is defined as minimum saturation output voltage of all effective pixels. Note 5: Definition of SE : SE = VSAT lx*s R Note 6: VMDK is defined as maximum dark signal voltage of all effective pixels. Note 7: Definition of DR : DR = VSAT VMDK VMDK is proportional to tINT (Integration time). So the shorter tINT condition makes wider DR value. Note 8: DC signal output voltage and DC compensation output voltage are defined as follows: 2001-02-16 3/13 TCD1205D OPERATING CONDITION CHARACTERISTIC Clock Pulse Voltage Shift Pulse Voltage "H" Level "L" Level "H" Level "L" Level Reset, Boost Pulse Voltage "H" Level Integration Clear Gate Voltage "H" Level "L" Level "L" Level Power Supply Voltage SYMBOL V VSH VRS, VBT VICG VOD MIN TYP.

Window Glass The dust and stain on the glass window of the package degrade optical performance of CCD sensor. Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the surface, and allow the glass to dry, by blowing with filtered dry N2. Care should be taken to avoid mechanical or thermal shock because the glass window is easily to damage. 2. Electrostatic Breakdown Store in shorting clip or in conductive foam to avoid electrostatic breakdown. 3. Incident Light CCD sensor is sensitive to infrared light. Note that infrared light component degrades resolution and PRNU of CCD sensor. 4. Lead Frame Forming Since this package is not stout against mechanical stress, you should not reform the lead frame. We recommend to use a IC-inserter when you assemble to PCB. 2001-02-16 12/13 TCD1205D PACKAGE DIEMENSIONS WDIP22-G-400-2.54A (D) Unit: mm Note 1: No. 1 SENSOR ELEMENT (S1) TO EDGE OF PACKAGE.
