ROHM LSH3008

Add-on Structure Contact Image Sensor Heads
LSH3008-CA10A
The Basic CIS by which the add-on can shorten the development period of a product sharply while being
able to satisfy broad demand. A taper glass and tempered glass can respond as an option.
As a measure against a paper jam, the custom-made correspondence of the special cantact plate can be
carried out.
Applications
Document Scanners,Bill sorters.Wide Format Scanners,and Lottery.
Features
1) Signal amplifier integrated into each sensor IC in order to eliminate external noise ; compatible with 3.3V interface.
2) LED light source mounted on the same substrate as the sensor chip itself, resulting in a more compact, lightweight package.
3) Proprietary prism maintains a uniform output signal.
