AN22011A
3-beam MD system pre-amplifier
■ Overview
The AN22011A incorporates such functions as RF
signal processing, servo signal processing, ADIP signal
processing and laser control. This is an RF IC that can
constitute the MD system using 3-beam pick-up in com-
bination with the digital signal processing LSI MN66621.
The IC allows us to achieve a considerable low power
dissipation as well as its low supply voltage operation
(V_CC = 2.1 V to 3.6 V) due to our introduction of digital
matrix (P_D = 11 mW at V_CC = 2.1 V). The IC can be used
in a wide range of applications from a stand-alone system
to a portable system.
