Operational Description
(The values shown below are design values when supply voltageV
CC
=5V.)
RF Amplifier
As shown in Figure 1, RF signals are generated by three-beam method pick-up. Equivalent resistance to RFOUT (Pin7) is
57.6k
, when resistance between RF– and RFOUT is 12k
.

Focus Error Amplifier
As shown in Figure 2, the operation result of (A+C) – (B+D) is outputted to FEOUT (Pin27). Equivalent resistance to FEOUT
is 96k
, when resistance between FE and FEOUT is 20k
