AMIS-732128, AMIS-732256, AMIS-732512 50µm-pitch Wide Aperture Spectroscopic Photodiode Arrays Data Sheet 1.0 Description AMI Semiconductor’s WSN series is a family of self-scanning photodiode solid-state linear imaging arrays. These photodiode sensors employ AMI Semiconductor’s proprietary CMOS image sensing technology to integrate the sensors into a single monolithic chip. These sensors are optimally designed for applications in spectroscopy. Accordingly, these sensors contain a linear array of photodiodes with an optimized geometrical aspect ratio (50µm aperture pitch x 2500µm aperture width) for helping to maintain mechanical stability in spectroscopic instruments and for providing a large light-capturing ability. The family of sensors consists of photodiode arrays of various lengths - 128, 256 and 512 pixels. The WSN photodiode arrays are mounted in 22-pin ceramic side-brazed dual-in-line packages that fit in standard DIP sockets. A diagram of its pin out configuration is seen in Figure 1. ..

AMIS-732128, AMIS-732256, AMIS-732512 50µm-pitch Wide Aperture Spectroscopic Photodiode Arrays Data Sheet 3.0 Sensor Characteristics AMI Semiconductor’s self-scanned WSN photodiodes are spaced on a 50µm pitch. The line density is 20 diodes/mm and accordingly the overall die lengths of the different arrays vary with the number of photodiodes. For example, the 128 pixel array is 6.4mm long,...
