Notes
1.
This value depends strongly on the application. The specified value is the typical value obtained using the application
diagram as illustrated in Fig.8.
At start-up of the OSCAD oscillator.
At start-up of the OSC48 oscillator.
Exclusive the IDDE current which depends on the components connected to the I/O pins.
