Data Sheet

ADuM4120/ADuM4120-1

SPECIFICATIONS

ELECTRICAL CHARACTERISTICS

Low-side voltages referenced to GND

. High-side voltages referenced to GND₂; 2.5 V ≤ V_DD1≤ 6.5 V; 4.5 V ≤ V_DD2≤ 35 V, and T = −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, and V_DD2= 15 V, unless otherwise noted.
