NOTES:
19. 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.
20. Full scale output current temperature coefficient (TFS) is given by delta (full scale output current)/(T).
21. Zero-scale error (ZS) is the deviation from zero current output when the digital input code is zero.
22. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
HFM (High Frequency Modulator) Standard conditions unless otherwise noted.
