3. FOCUS, TRACKING ACTUATOR, SLED MOTOR DRIVE PART
• The reference voltage REF is given externally through pin 23.
• The input signal, pin3,20,25 is amplified by R2 / R1 times and then fed to the level shift circuit.
• The level shift circuit produces the differential output voltages and drives the two output power amplifiers. Since the
• If the total gain is insufficient, the external resistors can be used through pin 4, 24 to increase the gain. The bias voltage
4. TRAY MOTOR DRIVE PART
differential gain of the output amplifiers is equal to 2 (1+ R4 / R3), input signal is amplified by (R2 / R1) 2 (1 + R4 /
R3).
(Vref) is about a half of the supply voltage(VM).
