5 / 8 page 344 Optical disc ICs BA6398FP FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 8V, f = 1kHz, RL = 8Ω) FCircuit operation (1) Driver Inputs to the IC are the focus tracking error signal from the servo preamplifier and the control signal from the mo- tor. The input signals, which normally center on 2.5V, are V / I converted by the preamplifier, generating a current corresponding to the input voltage. This current is passed through a resistor and into the internal reference voltage component, the preamplifier output being a sig- nal centering on the internal reference voltage. Two sys- tems (positive phase and negative phase) are created during V / I conversion, generating BTL output via the driver buffer. |
