These parts are designed and adjusted for accuracy with all errors in the voltage loop included. 7. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design. Electrical Specifications Recommended operating conditions, VCC = 3.3V, unless otherwise specified. Boldface limits apply across the operating temperature range -40°C to +85°C.
