Datasheet ADuM4138 (Analog Devices) - 4

ADuM4138 Data Sheet SPECIFICATIONS ELECTRICAL CHARACTERISTICS
Low-side voltages referenced to GND1 and high-side voltages referenced to GND2. VDD1 = 12 V, VDD2 = 16 V, TA = −40°C to +125°C, unless otherwise noted. All minimum and maximum specifications apply over the entire recommended operating junction temperature range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = 12 V, and VDD2 = 16 V, unless otherwise noted.
