The AN2516S has all the functions of the AN2515S except HD and VD output, and has attached γ-correction (which compensates luminance characteristics). It is easy to make up a 0.5-inch electronic view-finder with minimal external components. ■ Absolute Maximum Ratings (Ta=25˚C) Symbol Rating Supply voltage Parameter VCC 5.5 Unit V Supply current ICC 47 mA mW Power dissipation Note 2) PD 190 Operating ambient temperature Note 1) Topr –20 to +75 ˚C Storage temperature Note 1) Tstg –55 to +125 ˚C Note 1) Ta=25˚C except operating ambient temperature and storage temperatures unless otherwise specified.
