Other Parts Discussed in Thread: PCA9306
Hi all,
I have a question about PCA9306 "EN/VREF2" current.
In the data sheet of PCA9306 is written as follows,
"the EN input must be connected to VREF2 and both pins pulled to high-side VDPU through a pullup resistor (typically 200 kΩ)."
and Although it is introductory notes of the conversion to 3.3V from 1.8V at "Figure 2. Typical Application Circuit",
and so, Does the voltage to change need to change the constant of resistance (200koohm) in the following case?
For example, 1.2V<=>1.8V conversion or 3.3V<=>5V conversion.
Moreover, based on what kind of calculation is it considered as the constant 200kohm?
Best regards,
Hisa Kobayashi.
