AN2018S Correlated Double Sampling IC s Overview The AN2018S is used to reduce noise in CCD image sensor output signal. It performs correlated doublesampling on image signal sent from a CCD sensor to output clearer image signal. 0.4 0.4±0.25 5.0±0.3 0.3 4.2±0.3 6.5±0.3 8-Pin SOP Package (SOP008-P-0225) Unit:mm 0.1±0.1 1.27 Operating on low voltage (V CC=4.8V), consuming little current (ICC =12.7mA typ.) Including a high-speed sampling circuit responding to 510-830H CCD
