n overview the AN2145NFHP is a ccd video camera signal processor ic for 510h ccd. it incorporates full chroma signal lpfs and horizontal aperture correc- tion circuits. because carrier-balance is rationalized and ajustment-free, adjustments and necessary exter- nal components are reduced half in number as com- pared with conventional versions of ours. the an2146fhp is for 670h ccd, and the an2147fhp is for 768hccd. n features ? improved color reproduction with 4-channel white balance ? built-in high-luminance color-suppression circuit ? improved s/n ratio at low brightness AN2145NFHP, an2146fhp, an2147fhp ccd video camera signal processor ics 12.0 0.2 14.0 0.2 12.0 0.2 14.0 0.2 unit:mm 80-pin qfh package (qfh080-p-1212) (0.5) (min0.25) 1.3 0.1 1.3 0.1 2.8 0.2 0.15 ?0.05 + 0.1 0.1 0.1 0.5 0.2 1 parameter symbol rating unit v cc i cc p d t opr t stg 100 357 ?0 to +75 ?5 to +125 supply voltage supply current power dissipation note 2) operating ambient temperature note 1) storage temperature note 1) 5.5 v mw ma ?c ?c note 1) ta=25?c except operating ambient temperature and storage temperatures unless otherwise specified. note 2) allowable power dissipation of the package at ta=70?c. n absolute maximum ratings (ta=25 ?c) parameter symbol range operating supply voltage range v cc 4.4v to 4.8v n recommended operating range (ta=25?c)
