DEFINITIONS OF CHARACTERISTIC ITEMS

1. Saturation voltage: Vsat

Output signal voltage at which the response linearity is lost.

2. Saturation exposure: SE

Product of intensity of illumination (IX) and storage time(s) when saturation of output voltage occurs.

3. Photo response non-uniformity: PRNU

The peak/bottom ratio to the average output voltage of all the valid bits calculated by the following formula.

PRNU(%)=

VMAX. or VMIN.

5. Dark signal non-uniformity: DSNU

The difference between peak or bottom output voltage in light shielding and ADS.

6. Output impedance: ZO

Output pin impedance viewed from outside.

7. Response: R
