    Chapter 4 Appendix 4.1 Gain/Offset Calibration (AD368/DA364/DA374) Highly accurate measurement or output meeting the application environment as described below is possible by adjusting the gain and offset. AD368 example shown on section 1.2. (Example) When a ± 10V output connected equipment has 0.05 V offset when output voltage is zero and 9.95 V output voltage at maximum output, the relationship between the analog value input to AD368 and the count digitally converted by AD368 becomes as shown below after gain/offset calibration.
  • Page 88 Chapter 4 Appendix DA364 example shown on section 1.3. (Example) When the connected equipment maximum voltage is 9.95 V and offset is 0.05 V, the relationship between the count to DA364 and the analog value output from the DA364 becomes as shown below after gain/offset calibration.
