Datasheet ADuM4120/ADuM4120-1 (Analog Devices) - 3

Data Sheet ADuM4120/ADuM4120-1 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, and 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, and VDD2 = 15 V, unless otherwise noted.
