ON Semiconductor has introduced a CMOS image sensor to address the needs of biometric applications such as fingerprint detection as well as several medical device designs. The MANO 9600 is a rolling shutter 9.6 megapixel (MP) (3840 x 2500 pixel) device that runs at 20 frames per second (fps) at full resolution. MANO 9600, which complements ON Semiconductor’s existing range of image sensor products, utilizes new technology to help it achieve a maximum SNR performance of 41 decibels (dB) ) without the need for oversampling.

Available in both monochrome and color versions, the device achieves high frame rates in either single region of interest (ROI) or sub-sampled readout modes. Image data is read out through gain and offset amplifiers before being fed to an on-board 10-bit analog-to-digital-converter (ADC). The digital data is then transferred over four industry-standard low-voltage differential signaling (LVDS) outputs; a version with a single 10-bit CMOS output is also available.

An on-board sequencer, programmable over a serial peripheral interface (SPI), generates all internal timing for exposure control and also supports readout mode. Numerous other on-chip features such as a charge pump, fixed pattern noise (FPN) correction and bias control for power supply regulation help simplify implementation of the device into customer applications and reduce overall component counts. Power consumption is 500mW at 20fps, and 200mW at 5fps. Operating temperature range is 0 ºC to +70ºC.
