ELIS-1024
Enhanced High Performance Linear CMOS Image Sensor
The ELIS-1024 image sensor is a high performance, very low noise linear image sensor designed for a
wide variety of applications including:
P/N: ELIS-1024A-LG
16-pin LCC package
• Spectroscopy
• Bar Code Reading
• Edge Detection
• Contact Scanning
• Optical Character Recognition
• Encoding
• Position Detection
• And more.......
Description
The ELIS-1024 Linear Image Sensor consists of an array of high performance, low dark current photo-
diode pixels. The sensor features sample and hold capability, selectable resolution and advanced power
management. The device can operate at voltages as low as 2.8V making it ideal for portable
applications. A key feature over traditional CCD technology is that the device can be read and reread
Non-Destructively, allowing the user to maximize signal to noise and dynamic range. Internal logic
automatically reduces power consumption when lower resolution settings are selected. A low power
standby mode is also available to reduce system power consumption when the imager is not in use.
Key Features
• Low Cost
• Single Voltage Operation, Wide Operating Range
• Selectable Resolutions of 1024, 512, 256 and 128 pixels
• Very Low Power via Intelligent Power Management and Low-Power Standby Mode
• Sample and Hold
• Full Frame Shutter and Dynamic Pixel Reset (DPR) Modes
• High Sensitivity
• High Signal to Noise, very low dark current
• Non-Destructive Read mode, extremely low noise capable via signal averaging
• Completely Integrated Timing and Control

Resolution Selection
By setting the M0 and M1 inputs as indicated in Table 1, several effective resolutions can be realized.
The effective imager length is 7.987mm regardless of the selected resolution. Internally, the device has
1024 pixels. As the resolution decreases the effective pixel area increases as in Table 1. When the
resolution is set to 512, the photodiodes of pixels 1 and 2 are averaged and output as a single value,
pixels 3 and 4 are averaged and output as a single value, and so on. If set to 256 resolution, then pixels
1 through 4 are averaged and output as a single value, 5 through 8 are averaged and output as a single
value, and so on. The internal control logic determines the resolution and always outputs a valid pixel
per clock cycle. For example, if the imager is selected for 256-pixel resolution, then only 256 clock
cycles are needed to read out the imager once DATA is set. Thus, for lower resolutions higher frame
rates are possible as indicated in Table 1.

Power Management and Standby Mode
This device incorporates internally controlled power management features and an externally controlled
low-power Standby Mode. When resolutions lower than 1024-pixels are selected, internal logic disables
the unused amplifiers reducing the power consumption. Utilizing the existing external signals RST and
DATA a low-power Standby Mode is possible. When RST and DATA are simultaneously held high the
entire imager is put into Standby Mode. In this mode all internal amplifiers are disabled, the internal
clocks are stopped and the output amplifier is also disabled. The clock can be held low or high or
remain running while the imager is held in standby.
