IMAGE SENSOR
NMOS multichannel detector head
C8892
Integrated low-noise driver/amplifier circuit for NMOS linear image sensor
C8892 is multichannel detector head incorporating low-noise driver/amplifier circuit developed for Hamamatsu NMOS linear image sensors. C8892 is designed especially for compactness, having an overall length as short as 40 mm or less. In addition, C8892 is designed for ease of use. It is provided with circular flange for connection to monochrometer and adjustment mechanism for optical alignment for NMOS linear image sensor. The flange is interchangeable, thus facilitating connection to various models of monochrometer. The housing case also provides a shielding effect against external noise. As useful options, peripheral devices are available for driving C8892, and for the output signal processing.

*Video data rate is 1/6 of master clock frequency (62.5 kHz Max.). *The operation of circuit stroke length below 4.5 mm is recommended. *The relation between data video output voltage and output charges from NMOS image sensor can be expressed by the following formula.
Vout (V) = 3 x Output charge 10 x 10-12[F]
Note) Amplifier saturation voltage is 10 V.
