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
