CD FOCUS TRACKING SERVO LSI
The TA2031F is a 3-beam type PUH compatible focus
tracking servo LSI to be used in the CD player system.
(Compatible with the Foucault's method focus error
detection PUH with generally low focus error detecting
sensitivity.)
In combination with a CMOS single chip processor
TC9236AF, a CD player system can be composed very
simply.
FEATURES QFP44-P-1010-0.80C
o Built-in RF amp, focus error amp, and tracking error amp. Weight : 0.5g mm)
o Built-in focus tracking servo amp.
It Built-in phase compensation amp and LPF amp.
It Built-in ALPC amp.
0 Connections between PUH and power driver IC for motor driver allow simplified structuring of CD
player system.
Directly connectable to BTL amp (TA8192F) or PWM driver (TA8460F).
