AN2145NFHP, AN2146FHP, AN2147FHP CCD Video Camera Signal Processor ICs ■ Overview 12.0±0.2 14.0±0.2 Unit:mm 1 0.2 (0.5) (min0.25) 12.0±0.2 ■ Features 1.3±0.1 0.15 +– 0.1 0.05 1.3±0.1 2.8±0.2 0.5 0.1±0.1 The AN2145NFHP is a CCD video camera signal processor IC for 510H CCD. It incorporates full chroma signal LPFs and horizontal aperture correction circuits. Because carrier-balance is rationalized and ajustment-free, adjustments and necessary external components are reduced half in number as compared with conventional versions of ours. The AN2146FHP is for 670H CCD, and the AN2147FHP is for 768HCCD. 14.0±0.2 • Improved color reproduction with 4-channel white balance • Built-in high-luminance color-suppression circuit • Improved S/N ratio at low brightness 80-Pin QFH Package (QFH080-P-1212) ■ Absolute Maximum Ratings (Ta=25 ˚C) Parameter Symbol Rating Unit Supply voltage VCC 5.5 V Supply current ICC 100 mA mW Power dissipation Note 2) PD 357 Operating ambient temperature Note 1) Topr –20 to +75 ˚C Storage temperature Tstg –55 to +125 ˚C Note 1) Note 1) Ta=25˚C except operating ambient temperature and storage temperatures unless otherwise specified.
