ROHM LSH1208-BA50A Technical data
Color Contact Image Sensor Heads for High-speed Scanner
LSH1208-BA50A
Contact Image Sensor Heads with 3 times higher scanning speed due to 3ch outputs.
Newly developed resolution change-over IC is employed which has improved noise resistance.
Applications
High speed reading equipment (i.e. document scanners, wide format scanners).
Features
1) High speed reading capability due to 3 analog output.
2) Signal amplifier is built into the sensor IC in order to increase immunity to external noise.
3) ROHM’s newly developed sensor IC reduces failures due to ESD (based on the IEC61000-4-2 standard).
4) With the proprietary prism, the output signal is maintained uniformly.
5) The ceramic substrate is used for excellent dimensional accuracy and thermal stability.
