1
AD539x-3 products are calibrated with a 1.25 V reference. Temperature range for all versions: −40°C to +85°C.
2
Guaranteed by characterization, not production tested.
3
Programmable either to 1.25 V typical or 2.5 V typical via the AD539x control register. Operating the AD539x-3 products with a reference of 2.5 V leads to a
degradation in performance accuracy.
4
Accuracy guaranteed from VOUT = 39 mV to AV
