High-pixel resolution of 750 x 400 is combined with an RS-232 image output speed up to 60 frames per second. The IC combines low, fixed-pattern noise with a very high signal-to-noise ratio (SNR) and employs built-in compensation techniques to minimize high temperature leakage. The IC can be used at temperatures ranging from -40 ºC to 105 ºC.

A key element in the AMIS IC implementation has been the use of the Photonfocus LinLog technology. LinLog overcomes the drawbacks of pure logarithmic image sensors by using a linear response at low illumination levels and logarithmic compression at high intensities. Transition between the two is optimized to prevent artifacts and discontinuities. The use of linear response at low light levels increases the signal swing at the output of the pixel to maximize sensitivity. In addition it reduces the effects of fixed pattern offset and gain noise associated with logarithmic sensors. The Photonfocus LinLog technology contributes to the IC's high dynamic range and ensures acquisition of high-contrast images without image lag or smear--even at high frame rates. In addition, the LinLog 'global shutter' capability enables fast-moving scenes to be captured without motion artifacts.

Available now in production quantities, the AMIS-70700 can be supplied as bumped and un-bumped probed wafers. A ceramic CLCC 52-pin package option, suitable for use in harsh environments, is also available. The pricing is $52 in sampling quantities.
