TA2157F,TA2157FN Digital Servo Head Amp for CD System
TA2157F/FN is a digital servo head amp for a 3-beam pickup
used in CD systems.
Gain for RF signal generation amp can be freely set, supporting
CD-RW.
Combining with single-chip processor TC94A14F/FA/FB, a
CMOS digital servo, makes configuring CD systems simple.
