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

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.
