Re: Frequency Resolution of max038

Well,I looked through the data*** again and found that it is the
current at pin IIN that partly determine the frequency.
So the current from the output of the DAC,which is connected to the pin
IIN,will control the output frequency of MAX038.
I think it will be another way to control frequency instead of using
resistors,and it will be more easily manipulated by MCU.
What is your suggestions?
Thanks.


Ok. what I wasn't able to figure out was the burden
voltage of the IIN current input. So, you supply a
current from 2uA to 500uA. This gives you a decade
of frequency roughly. Meaning, you have to switch
capacitors. You'll need about 3 caps to switch.
