About ADC input impedance of i.MX25

Dear all,

 

Would you teach the input impedance value for ADC ports of i.MX253?
(Max value and Min value)


We investigate the output resistance value of the external device connected to ADC port.
We investigate a measurement error when we changed the output resistance from 10 Ω to 100kΩ.

 

Best Regards,
Yuuki
