I am using AD5726. On the datasheet there is reference input current (pag.3), for VREFN there is written -1mA (max).My question is: should I consider 1mA going inside the chip or 1mA coming from the chip ? What does minus means ?Thanks.Lucio
From the part's point of view, if the input current is negative then the current is coming from the part. This would make sense if the pin (i.e. AVSS) is below 0V.
