TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC 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.) NN In combination with a CMOS single chip processor SS NN oe TC9236AF, a CD player system can be composed very Mi me AS simply. eK sss FEATURES QFP44-P-1010-0.80C © Built-in RF amp, focus error amp, and tracking error amp. Weight : 0.59 (Typ.) © Built-in focus tracking servo amp. @ Built-in phase compensation amp and LPF amp. @ Built-in ALPC amp. @ 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). 9809 10EBA. @ TOSHIBA is continually working to improve the quality and the reliability of its products.
