CCD(Charge Coupled Device)
TCD1304DG
The TCD1304DG is a high sensitive and low dark current 3648
−elements linear image sensor. The sensor can be used for POS
scanner.
The device consist of sensitivity CCD chip.
The TCD1304DG has electronic shutter function (ICG).
Electronic shutter funtion can keep always output voltage
constant that vary with intensity of lights.

Note 2: Measured at 50% of SE (Typ.)
Definition of PRNU: PRNU =
()%100×χ
χ∆
Where χ is average of total signal outputs and χ∆is the maximum deviation from χ under uniform illumination.
Note 3: Measured at 50% of SE (Typ.)
RI is defined as follows:
RI = ()%100·36473647
1n 1n n ×χ
∑=+χ−χ
Where χ n and χ n+1 are signal outputs of each pixel.χis average of total signal outputs.
Note 4: V SAT  is defined as minimum saturation output voltage of all effective pixels. Note 5: V MDK  is defined as maximum dark signal voltage of all effective pixels.
Note 6: Definition of DR : DR =

V SAT
V  V MDK  is proportional to t INT  (Integration time).
So the shorter t INT  condition makes wider DR value.
