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
I would also like to ask: what does it appen if VREFP - VERFN < 2.5 V ?
On the datasheet it says it must be at least 2.5V, but my shunt voltage reference is 2.5V with initial tolerance of 20mV. Is it an issue ?
Thanks, best regards,
