Hi,
I'm trying to develop an 8.2k resistor(8k2) comparator pin. What is the best way to do this with low current consumption?
I try with a voltage divider but it gave a high consumption because even just reading the pin a few times per second, the R5 is connected to the GND and consumes all the time that the 8k2 resistor is connected.
Voltage divider circuit:
This give me a consumption of about 0.4-0.5mA. I need a consumption below 0.05mA.
What is the best technique to use in this case?
Best regards.
