Data Sheet

ADuM4121/ADuM4121-1

SPECIFICATIONS

ELECTRICAL CHARACTERISTICS

Low-side voltages referenced to GND₁. High side voltages referenced to GND₂; 2.5 V ≤ V_DD1≤ 6.5 V; 4.5 V ≤ V_DD2≤ 35 V, T_J= −40°C to

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

specifications are at T_J= 25°C, V_DD1= 5.0 V, V _DD2= 15 V.
