Preliminary Technical Data
ADuM5000
ELECTRICAL CHARACTERISTICS – 5V PRIMARY INPUT SUPPLY / 3.3V SECONDARY ISOLATED SUPPLY¹
4.5 V ≤ VDD1 ≤ 5.5 V, VSEL= GNDISO, all voltages are relative to their respective ground. All min/max specifications apply over the entire
recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD = 5.0 V, VISO = 3.3 V, VSEL=
GNDISO.
