Parameter Symbol Min Typ Max Unit Test Conditions/Comments Resistance (Input to Output)1 RI-O 1013 Ω Capacitance (Input to Output)1 CI-O 2 pF f = 1 MHz Input Capacitance2 CI 4.0 pF IC Junction-to-Ambient Thermal Resistance θJA 76 °C/W Thermocouple located at center of package underside 1 The device is considered a 2-terminal device: Pin 1 through Pin 10 are shorted together, and Pin 11 through Pin 20 are shorted together. 2 Input capacitance is from any input data pin to ground. REGULATORY INFORMATION The ADuM7640/ADuM7641/ADuM7642/ADuM7643 are approved by the organizations listed in Table 14. See Table 18 and the Insulation Lifetime section for recommended maximum working voltages for specific cross-isolation waveforms and insulation levels. Table 14. UL (Pending) Recognized Under UL 1577 Component Recognition Program1 Single Protection,1000 V rms Isolation Voltage File E274400 1 In accordance with UL 1577, each ADuM7640/ADuM7641/ADuM7642/ADuM7643 is proof tested by applying an insulation test voltage ≥ 1200 V rms for 1 sec (current leakage detection limit = 5 µA).
