† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The VSP2270 device is a complete mixed-signal processing IC for digital cameras providing signal conditioning and analog-to-digital conversion for the output of a charge-coupled device (CCD) array. The primary CCD channel provides correlated double sampling (CDS) to extract the video information from the pixels, 6-dB to 42-dB gain range with digital control for varying illumination conditions, and black level clamping for an accurate black level reference. Input signal clamping and offset correction of the input CDS are also performed. The stable gain control is linear in dB. Additionally, the black level is quickly recovered after gain change.

The VSP2270Y device is available in a 48-lead LQFP package and the VSP2270M device is available in a 48-lead P-VQFN package. Both devices operate from a single 3-V/3.3-V supply.
