PGA281: Data sheet

Naser S.
Genius 11605 points

Part Number: PGA281

In PGA281 data sheet "logic low threshold" minimum for "digital I/O" (see datasheet pag 5).


Datasheet  reporting  0,1V as minimum voltage, is it possible to connect the pin to GND directly? Or it would be necessary to use an impedance to GND? In affirmative what value of impedance? Can someone  please give us confirmation quickly as customer has been waiting with no replies. Thanks.

    Hi Naser,
    That 0.1V minimum is the minimum threshold at which the PGA281 will detect a low logic level, not the minimum voltage which can be applied to the pin. As long as your input voltage is lower than the 0.1V minimum, the PGA281 will detect it as a "0".
