ADuM4121/ADuM4121-1

Rev. 0 | Page 3 of 16

SPECIFICATIONS

ELECTRICAL CHARACTERISTICS

Low-side voltages referenced to GND1. High side voltages referenced to GND2; 2.5 V ≤ VDD1 ≤ 6.5 V; 4.5 V ≤ VDD2 ≤ 35 V, TJ = −40°C to

+125°C. All minimum/maximum specifications apply over the entire recommended operating range, unless otherwise noted. All typical

specifications are at TJ = 25°C, VDD1 = 5.0 V, VDD2= 15 V.
