ESP8266 Community Forum

- Sat Mar 26, 2016 8:06 am #44060 I've been looking for information on pin resistance of the ESP8266 , and have had no luck
The datasheet I've found are quite lacking in this area.
Does anybody know the following....

ADC pin input Resistance = ?
GPIOx Output Resistance = ?
GPIOx Input Resistance = ?

- Sat Mar 26, 2016 8:17 am #44063 The specs mentioned :

GPIO outputs 12ma max current
GPIO inputs 50uA leakage current

Nothing mentioned about ADC Tout.

- Sat Mar 26, 2016 8:33 am #44066 Ok so how can I get the Resistance 3.3V ----R-----12MA----load------gnd

50ua leakage Equates to what Resistance ? 3.3v ------R leakage-- pin volts?

I don't think I have the resources to measure correctly.......

V = R * I
