NOTES
1Temperature range for A Version: –40
°C to +85°C
2Guaranteed by characterization. Not production tested.
3The AD7839 is functional with power supplies of
± 12 V ± 10% with reduced output range. At 12 V it is recommended to restrict reference range to ± 4 V due to
output amplifier headroom limitations
Specifications subject to change without notice.
