DATA SHEET
MOS INTEGRATED CIRCUIT
µPD8670A
7400 PIXELS CCD LINEAR IMAGE SENSOR
The µ PD8670A is a high sensitive and high-speed CCD (Charge Coupled Device) linear image sensor which changes
optical images to electrical signal.
The µ PD8670A is a 2-output type CCD sensor with 2 rows of high-speed charge transfer register, which transfers the
photo signal electrons of 7400 pixels separately in odd and even pixels. And it has reset feed-through level clamp circuits
and voltage amplifiers. Therefore, it is suitable for 600 dpi/A3 high-speed digital copiers, multi-function products and so on.
FEATURES
• Valid photocell : 7400 pixels
• Photocell pitch : 4.7 µ m
• Photocell size : 4.7 × 4.7 µ m2
• Resolution
: 24 dot/mm (600 dpi) A3 (297 × 420 mm) size (shorter side)
• Data rate
: 44 MHz MAX. (22 MHz/1 output)
• Output type
: 2 outputs in-phase operation, and out of phase also supported
• High sensitivity : 17.0 V/lx•s TYP. (Light source: Daylight color fluorescent lamp)
• Peak response wavelength : 550 nm (green)
• Low image lag : 1 % MAX.
• Drive clock level : CMOS output under +5 V operation
• Power supply : +12 V
• On-chip circuits : Reset feed-through level clamp circuits
: Voltage amplifiers

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.
