These parts are designed and adjusted for accuracy with all errors in the voltage loop included. Verified by design and/or characterization. 7. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design. Recommended operating conditions, VCC = 3.3V, unless otherwise specified. Boldface limits apply across the operating ambient temperature range -40°C to +85°C. (Continued) Parameter Test Conditions Min (Note 7)Typ Max (Note 7)Unit |
