hello team
Reffered to the datasheet of OPA2320-Q1, if use dual-supply, recommend range is ±0.9V to ±2.75V;
Is it ok for me to use asymmetrical power supply such as +3.3 for V+, and -2.1V for V-, still in Vs range?
and if there are some bad effect?

Of course you can, this is all about I/O headrooms not specific supply values, Bruce Trump covered this in the 1st 3 sections of this excellent series,

Hi User,
Michael is correct, asymmetrical supplies are okay so long as you are operating within the common mode input range and output swing.
