Ordering number : ENA2118A LC898212XA CMOS LSI AF Control LSI Overview The AF control device, LC898212XA (LC898212XA-MH), provides an ideal way to implement the reduced power consumption and the improved autofocus precision and speed (reduced convergence time) required in high-pixelcount camera modules for use in smartphones.
The LC898212XA integrates on a single chip an equalizer circuit employing digital calculation, and it can be combined with position sensors to build a closed-loop actuator control system.
Since closed-loop control provides better ability to maintain the control object than conventional open-loop systems and is not affected by position differences, the LC898212XA is i...
