Output current is limited by device thermal dissipation. 10. Percentage of Full Scale (FS) with temperature compensation applied. 11. VOUT measured at the termination of the VSENP and VSENN sense points. 12. For operation at 400kHz, see PMBus™ Power System Management Protocol Specification Part 1, Section 5.2.6.2 for timing parameter limits. 13. Does not include errors due to resistor divider tolerances. 14. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design. Electrical Specifications VDD = 12V. Typical values are at TA = +25°C. Boldface limits apply across the operating ambient temperature range, TA -40°C to +85°C.
