AMI Semiconductor has announced a 2400dpi CMOS image sensor. The  AMIS-722402 allows the selection of 2400, 1200, 600, or 300dpi resolutions. Based on AMI Semiconductor’s proprietary CMOS image sensing technology, the sensor combines, on a single IC, 1376 active pixels with an on-chip output amplifier, power down circuitry and parallel transfer functionality. Sensors are designed to be cascaded end-to-end on a PCB and packaged in an image-sensing module. The AMIS-722402 incorporates a number of features designed to ensure optimum performance. These include a pixel-to-pixel offset cancellation circuit that reduces fixed pattern noise (FPN) and amplifier offsets while improving optical linearity and low noise sensitivity. A parallel "integrate, transfer and hold" feature optimizes sensor response by allowing sensor read out to occur at the same time as photon integration.

Designed to operate from a 3.3V power supply, the AMIS-722402 incorporates a power saving feature that minimizes power consumption when multiple sensors are cascaded together to form a linear imaging array. Sensor resolution is selected via two "select resolution inputs" and, unlike a CCD array, all resolutions can operate with the same clock frequency equal to the pixel rate frequency.

The AMIS-722402 is currently available at a price of $0.25, with a minimum order quantity of 5,000 die.
