Dear team,

 

I would like to ask about analog input pins of i.MX25.

(1)

Can I understand that the maximum input range of INAUXx pins of i.MX25 is NVCC_ADC+0.3V?

(2)

My customer plans to rise NVCC_ADC at 1mS after the rising of NVDD_GPIO on their i.MX25 board.

The both of the voltage level are 3.3V.

Is it possible to input 3.3V into INAUXx pins during the 1mS, before the rising of NVCC_ADC and after the rising of NVDD_GPIO?

I think that the 3.3V into INAUXx pins has to be input after the rising of NVCC_ADC.

 

Thanks,

Miyamoto
