ADC0808-N: Input Current at Any Pin of the absolute maximum rating

Part Number: ADC0808-N

Dear Support team,

The absolute maximum ratings in the ADC0820-N data sheet have a item of Input Current at Any Pin.

Our customer will use ADC0808-N in their application.

What is the absolute maximum rating of Input Current at Any Pin of the ADC0808-N ?

Best Regards,
Hiroaki Masumoto

  • Hi Masumoto-san,

    The absolute maximum rating into any input pin is 1mA as you've noted.  As note 4 states, this current will only flow when the inputs are pulled above/below the power-supply voltages by more than a diode drop which causes the internal ESD protection cells to conduct.  These cells shouldn't have more than 1mA flowing through them in this case as the note suggests.

  • Hi Wells-san,

    Thank you for your reply.
    I understood and will inform our customer of your information.

    Best Regards,
