The VSP2560/62/66 are a family of complete mixed-signal processing ICs for digital cameras that provide correlated double sampling (CDS) and analog-to-digital conversion for the output of CCD arrays. The CDS extracts the pixel video information from the CCD signal, and the analog-to-digital converter (ADC) converts the digital signal. For varying illumination conditions, a very stable gain control of - dB to 44 dB is provided. The gain control is linear in dB. Input signal clamping and offset correction of the input CDS are also provided. Offset correction is performed by the optical black (OB) level calibration loop, and is held in calibrated black level clamping for an accurate black level reference. Additionally, the black level is quickly recovered after gain changes. The VSP2560/62/66 are available in LQFP-48 packages and operate from single +3 V supplies.

The VSP2582 is a complete mixed-signal processing IC for digital cameras that provides correlated double sampling (CDS) and analog-to-digital conversion (ADC) for the output of charge-coupled device (CCD) array. The CDS extracts video information of the pixels from the CCD signal, and the ADC converts it to a digital signal. For varying illumination conditions, –9 dB to +35 dB very stable gain control is provided. This gain control is linear in dB. Input signal clamping and offset correction of the input CDS are also provided. Offset correction is performed by an Optical Black (OB) level calibration loop, and held at a calibrated black level clamping for an accurate black level reference. Additionally, the black level is quickly recovered after a gain change. The VSP2582 is available in a QFN-36 package, and operates from a single +3 V supply. The RHH package features an exposed thermal pad, resulting in substantially improved thermal performance.
