Features • Data Rate up to 50 MHz (2 Outputs at 25 MHz Each) • Pixel Size: 10 µm x 10 µm (10 µm Pitch) • 300 to 1100 nm Spectral Range • High Sensitivity and Lag-free Photodiodes • Very Low Noise (30 pJ/cm2 Noise Equivalent Illumination) • Antiblooming • Exposure Control • 20-lead 0.4" DIL Package • Electrical, Mechanical and Optical Compatibility Between the Two Products The TH7813 and TH7814 linear arrays are based on Atmel’s most recent know-how in terms of design and technology. Flexibility and performance of these devices give the opportunity to use them in most vision systems for industrial applications (web inspec- tion, process control, sorting and inspection of various parts), document scanning up to 200 dpi, metrology, etc. Pin Identification All pins must be connected Pin Number Symbol 4, 17 VDD1,2 3, 18 VOS1,2 5 VS 20 VDR 2 VGS 14 ΦL1 13 ΦL2 15 ΦR 10 ΦA 7 VA 8 VST 11 ΦP 1, 6, 9, 12, 16, 19 VSS Function Output Amplifiers Drain Supply Video Outputs Output Amplifiers Substrate Bias Reset Drain Supply Output Gate Bias Readout Register Clocks Reset Clock Antiblooming Gate Bias/Clock Antiblooming Drain Bias Storage Gate Bias Transfer Gate Clock Ground, Optical Shield Grounding (Internally Connected) 50 MHz 1024/2048 Linear CCDs TH7813A TH7814A VSS VGS VOS1 VDD1 VS VSS VA VST VSS ΦA 1 20 2 19 3 18 4 17 5 TH7813A 16 6 TH7814A 15 7 14 8 13 9 12 10 11 VDR VSS VOS2 VDD2 VSS ΦR ΦL1 ΦL2 VSS ΦP Rev. 1990A–IMAGE–05/02 1 1 page TH7813A/TH7814A Figure 5.
