Usage Notes
• Power supply application timing
When applying power to the LC89902V, either both power-supply voltages must be turned on at the same time or V_CC
(+5 V) must be turned on before V_EE (–10 V) is turned on. The IC may be destroyed if V_EE is turned on first.
• Power supply noise elimination
Clock frequency noise may occur on the power supply lines due to the charge and discharge currents required to drive
the CCD. Capacitors must be inserted both between V_CC and ground and between V_EE and ground to eliminate noise
from the power supply lines. These capacitors must have values of at least 47 µF.
