Subject: -Vs connection


Part Number: AD8021


Linear Product Category: NA



Inquiry Description:

Just to double check, is it possible to connect the power supply (pin 4) to ground instead of the negative Vs value? All the design reference I saw (from UG727 document) connected the -Vs pin to a -ve voltage, but I'm constraint in terms of PCB area so I couldn't supply a negative voltage to the chip, hence I just want to double check if connecting -Vs to ground will still work. My input voltage range is from 0.2V to 3V, and my planned +Vs will be 5V.
