Product Summary

The AD7775BJR is lc2 mos complete embedded servo front end for HDD. It provides all the functionality necessary to implement the servo demodulator and head positioning tasks in embedded servo system.A power-down mode which turns all the linear circuity OFF enhances the use of the AD7775BJR in portable systems.
