NOTES:
14. Full scale output current power supply sensitivity (SFS) is measured by varying the V_SO from 4.5V to 5.5V DC and measuring the effect of this signal
on the full-scale output current.
15. Full scale output current temperature coefficient (TFS) is given by delta (full scale output current)/(T).
16. Zero-scale error (ZS) is the deviation from zero current output when the digital input code is zero.
17. PMAX bias overdriven via R_SET.
