DS1099
Low-Frequency Dual EconOscillator
_______________________________________________________________________________________
3
Note 1:
All voltages referenced to ground.
Note 2:
Active supply current combines the standby current with the output current. The output current is defined by
I = (CLOAD + 12pF ) x VCC x fOUT for each output when enabled.
Note 3:
This is the change observed in output frequency due to changes in temperature or voltage.
Note 4:
This parameter is guaranteed by design.
Note 5:
This indicates the time between power-up and the outputs becoming active.
