Brief Description

The DLIS-2K Linear Image Sensor consists of 4 rows of pixels, each with 2080 optical pixels and 16 dark pixels. Three rows are made up of 4 micron x 4 micron square pixels and the other is an array of rectangular 4 micron wide x 32 micron tall pixels with equivalent sensitivity ≤ 160 V/lux.s by utilizing Correlated Multi-Sampling (CMS). There is a 4 micron space between rows 1 & 2. One to four rows may be selected for readout. Each row has independent control of reset and integration. Additionally the background sample can be selected as the reset value for normal Correlated Double Sampling (CDS) or can be selected to be the ambient light sample with integration time controlled by the user. The sensor is programmable via a 3-wire serial interface and combined with our patented high speed Distributed 8 to 11 bit Analog to Digital Converter (D/AD ), XtremePIX®, and Active Column Sensor (ACS®) technologies to enable a powerful imaging combination for the most demanding applications.
