Auto Focus (AF) Controller & Driver
LC898217XH is the AF control LSI. It consists of 1 system of feedback
circuit for AF control. Built-in equalizer circuit using digital operation.
Built-in A/D converter, D/A converter, Constant Current Driver.
LC898217XH contains an internal EEPROM. It easily accomplishes
Hall calibration and power-on sequence. Also LC898217XH has fast
settling function for quickly moving focus lens. This is suitable for
small & thinner camera module.
