LSH3004-AA10A is a compact color contact image sensor head for narrow-width scanners produced by ROHM. This product integrates the signal amplifier on the sensor chip, which shuts out external noise and realizes high speed scanning with the newly developed analog memory circuit. The LED light source is mounted on the same substrate as the sensor chip, which makes it possible to package the device with lighter weight and an extremely small size. The proprietary prism(reflectors) maintains the output signal uniformly. The ceramic substrate is used for excellent dimensional accuracy and thermal stability.
The LSH3004-AA10A is a compact color Contact Image Sensor Head designed for rapid scanning of widths up to A6. It is intended for applications such as check readers, card scanners, and other image input devices used in photographic and office‑automation equipment.\n\nKey specifications include a 103 mm effective scanning width, 300 dpi dot density, 5 Vpp power supply, 0.5 ms/line scanning speed, and a 25 MHz clock. The device integrates an on‑chip amplifier, LED light source, and proprietary prism for uniform output, all mounted on a ceramic substrate for dimensional accuracy and thermal stability.
