NMOS multichannel detector head
C8892
Integrated low-noise driver/amplifier circuit
for NMOS linear image sensor
The C8892 is multichannel detector head incorporating low-noise driver/amplifier circuit developed for HAMAMATSU NMOS linear
image sensors. The C8892 is designed especially for compactness, having an overall length as short as 40 mm or less.
In addition, the 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 the C8892, and for the output signal processing.

Precaution for use
When operating the C8892 with the C7557-01, always be sure to attach the MOS adapter (supplied) to the C7557-01 main unit. If the
the C8892 is connected and the power is turned on without attaching the adapter, the power supply in the C7557-01 main unit may be
damaged.

*3: The operation of duty ratio 50 % Typ. is recommended.
*4: The outputs of start-pulse and clock-pulse are to be obtained from a front part where an image sensor is installed. The outputs of endof-scan and trigger-pulse are to be obtained from a back-side part where a connector for input/output signal is fixed.

· 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 ×
Output charge
10 × 10-12 [F]
Note: Amplifier saturation voltage is 10 V.
