*2: An increased current consumption at the video terminal rises the sensor chip temperature causing an increased dark current.
Connect a buffer amplifier for impedance conversion to the video terminal so that the current flowing to the video terminal is
minimized.
Use a JFET or CMOS input, high-impedance input op amp as the buffer amplifier.
*3: Storage time Ts=10 ms
*4: Voltage difference with respect to Vo, Ts=10 ms
*5: Uniformity is defined under the condition that the device is uniformly illuminated by light which is 50 % of the saturation
exposure level and using 510 pixels excluding both ends pixels as follows:
PRNU= ∆X/X × 100 (%)
X: the average output of all pixels, ∆X: difference between X and maximum or minimum output.
*6: Measured with a tungsten lamp of 2856 K.
