The accuracy of the external (U4) or internal reference sets the accuracy of the ADOC function. Total accuracy with a ±0.1% external reference is ±0.2% and ±0.5% with the internal reference. The 12V supply can go as low as 8V if the internal regulator is set to 3.6V. APPLICATIONS INFORMATION (CONTINUED) |
