This is a driver/amplifier circuit which can operate CMOS linear image sensors (S5461/S5462/S5463/S5464 series). It operates +5 V single
voltage supply and facilitates to control the external signal. Furthermore, it can be easily built-in to the instrument due to a small size. The pulse
generater (C5945) for operating this driver/amplifier is available upon request.
NOTE: C5863 does not include the sensor, which should be ordered separately.

Data rate=50 kHz
*1: Storage time Ts=100 ms
*2: For Low gain, the saturation output voltage and saturation exposure are determined by the saturation charge.
For High gain, the saturation output voltage and saturation exposure are determined by the upper output limit of the
integration amplifier.
*3: Measured with a tungsten lamp of 2856 K.
*4: Uniformity is defined under the condition that the device is uniformly illuminated by light which is 50 % of the saturation
exposure level as follows:
PRNU= (X/X) 100 (%)
Where X is the average output of all pixels and X is the difference between the maximum output and the average output X.
