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. Features Applications l Low noise l Wide dynamic range l Operatable with simple input signals l Multichannel spectrophotometry l Optical spectrum analysis l Time-resolved photometry (Only a master start pulse, a master clock pulse, 15 V are required.) l Interchangeable flange l Simple electrical and optical adjustments Compatible NMOS linear image sensors Type No. of NMOS linear image sensor *1 S3901-128Q, S8380-128Q S3901-256Q/F, S8380-256Q S3901-512Q/F, S8380-512Q S3902-128Q S3902-256Q/F S3902-512Q/F S3903-256Q S3903-512Q/F S3903-1024Q/F S3904-256Q, S8381-256Q S3904-512Q/F, S8381-512Q S3904-1024Q/F, S8381-1024Q *1: The suffix of type number indicates: Q: quartz window, F: fiber optic window Number of pixels 128 256 512 128 256 512 256 512 1024 256 512 1024 Active area per pixel (pixel pitch x height) 50 m x 2.5 mm 50 m x 0.5 mm 25 m x 0.5 mm 25 m x 2.5 mm 1 NMOS multichannel detector head C8892 Absolute maximum ratings Parameter Supply voltage (analog) Operating temperature Storage temperature *2: No condensation Symbol Va Topr Tstg Value 18 0 to 50 *2 -10 to 60 *2 Unit V C C Electrical characteristics (Ta=25 C) Parameter Supply voltage Analog Symbol Min.
