MOS INTEGRATED CIRCUIT
µPD3729
5000 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR
The µPD3729 is a high-speed and high sensitive color CCD (Charge Coupled Device) linear image sensor which
changes optical images to electrical signal and has the function of color separation.
The µPD3729 has 3 rows of 5000 pixels, and it is a 2-output/color type CCD sensor with 2 rows/color of charge
transfer register, which transfers the photo signal electrons of 5000 pixels separately in odd and even pixels.
Therefore, it is suitable for 400 dpi/A3 high-speed color digital copiers and so on.
FEATURES
• Valid photocell : 5000 pixels × 3
• Photocell's pitch : 10 µm
• Line spacing
• Color filter
: 40 µm (4 lines) Red line-Green line, Green line-Blue line
: Primary colors (red, green and blue), pigment filter (with light resistance 107 lx•hour)
• Resolution
: 16 dot/mm (400 dpi) A3 (297 × 420 mm) size (shorter side)
• Drive clock level : CMOS output under 5 V operation
• Data rate
: 30 MHz MAX. (15 MHz/1 output)
• Output type
: 2 outputs in phase/color
• Power supply : +12 V
• On-chip circuits : Reset feed-through level clamp circuits

5. Dark signal non-uniformity: DSNU
Absolute maximum of the difference between ADS and voltage of the highest or lowest output pixel of all the valid
pixels at light shielding. This is calculated by the following formula.
DSNU (mV) : maximum of dj ADS j = 1 to 5000
dj : Dark signal of valid pixel number j

6. Output impedance: ZO
Impedance of the output pins viewed from outside.
7. Response: R
Output voltage divided by exposure (Ixs).
Note that the response varies with a light source (spectral characteristic).
8. Image lag: IL
The rate between the last output voltage and the next one after read out the data of a line.
