Output swing of OPA859-Q1 when Operating from Single 3.3V Supply
I am using OPA859-Q1 in one of my applications. It's supply voltage is 3.3V,single supply operation.I am confused about is output swing when operated from 3.3V supply
Is the maximum swing is 2.4V when operated from 3.3V Supply.Below table is from datasheet '6.5 Electrical Characteristics'

In section 6.5 of the data sheet is the snippet of the table you put in your question but, you possibly failed to read the default words at the top of the section: -
$V_{S+} = 5 V, V_{S-} = 0 V$
This is the default power supply and, to get an output voltage of typically 4.1 volts, you need a supply of 5 volts. However, if $V_{S+}$ is only 3.3 volts then the typical output value will be 2.4 volts.
