ILX508A
7926-pixel CCD Linear Image Sensor (B/W)
For the availability of this product, please contact the sales office.
Description
The ILX508A is a reduction type CCD linear sensor
24 pin DIP (Ceramic)
developed for high resolution copiers. This sensor
reads A3-size documents at a density of 600 DPI (Dot
Per Inch). A built-in timing generator and clock-drivers
ensure direct drive at 5V logic for easy use. In
addition reset pulse can switch between internal
generation and external input.
Features
• Number of effective pixels: 7926 pixels
• Pixel size: 7µm × 7µm (7µm pitch)
• Built-in timing generator and clock-drivers
• Ultra high sensitivity
• Ultra low lag/low dark voltage
• Output method
• Maximum operating frequency: 12.5MHz

∗1 In accorcance with the given electrooptical characteristics, the even black level is defined as the mean
value of D8, D10, D12, D14, and D16.
∗2 For the sensitivity test light is applied with a uniform intensity of illumination.
∗3 W lamp (2854K).
∗4 PRNU is defined as indicated below. Ray incidence conditions are the same as for ∗2.

Where the 7926 pixels are divided into blocks of 102, even and odd pixels, respectively (Even and odd last
blocks are 87.) The maximum output of each block is set to VMAX, the minimum output to VMIN and the
average output to VAVE.
∗5 Use below the minimum value of the saturation output voltage.
∗6 Saturation exposure is defined as follows.
SE = VSAT
R1
∗7 Indicates the DC difference in value between odd black level and even black level.
∗8 optical signal accumulated time τ int stands at 10ms.
∗9 The difference between the maximum and mean values of the dark output voltage is calculated for even
and odd respectively. The larger value is defined as the dark signal nonuniformity.
Optical signal accumulated time τ int stands at 10ms.
∗10 VOUT = 500mV (Typ.)
