See DUTGND Voltage Range section.
Temperature range for A and B Versions: –40°C to +85°C.
Guaranteed by characterization. Not production tested.
The AD7841 is functional with power supplies of ± 12 V ± 10% with reduced output range. Output amplifier requires 2.5 V of head room at the bottom and top ends
of the transfer for function. At 12 V supplies it is recommended to restrict the reference range to ± 4 V.
