UPD3725A

DATA SHEET MOS INTEGRATED CIRCUIT µPD3725A 5000-BIT × 3 CCD COLOR LINEAR IMAGE SENSOR The µPD3725A is a high sensitivity 5000-bit × 3 CCD (Charge Coupled Device) color linear image sensor which changes optical images to electrical signal and has the function of color separation. The µPD3725A has 3 rows of 5000-bit photocell array and 6 rows of 2500-bit charge transferred register, so it is suitable for high resolution color image scanners and digital color copiers. FEATURES Valid photocell Line distance Color filter Resolution Data rate Power supply : 5000-bit × 3 : 112 µm (8 lines) R(red) bit-G(green) bit, Gbit-B(blue)bit : Primary colors (red, green and blue), pigment filter (with light resistance 107lxHour) : 16 dot/mm across the shorter side of a B4-size (257 × 364 mm) sheet : 16 MHz MAX. : +12 V Photocell's pitch : 14 µm Drive clock level : CMOS output under 5 V operation High speed scan : 320 µs/line CHANGED POINTS from the µPD3725D-01 Pins 18 and 15, 17 and 14, 11 and 8, 12 and 9 are each connected inside of the device (refer to BLOCK DIAGRAM). The specification of the total transfer efficiency (TTE) is improved from 92 % to 93.5 % (MIN.) (refer to ELECTRICAL CHARACTERISTICS).
