Note 1: Devices are 100% production tested at T

A

= +25°C and +105°C. Operation to -40°C is guaranteed by design.

Note 2: I

INL 100% production tested from 0 to 20mA only.

Note 3: I

DNL guaranteed by V

OUT

DNL.

Note 4: 0 to 20mA zero-scale current extrapolated by interpolation from full scale and code 192. See the

Measuring Zero-Code

Current (0 to 20mA Mode) section.

Note 5: OUTI voltage compliance measured at V

DDI

= +33.22V.

Note 6: When updating the DAC registers, allow 5µs before sending the next command.
