4 / 12 page ADuM1234 Rev. 0 | Page 4 of 12 PACKAGE CHARACTERISTICS Table 2. Parameter Symbol Min Typ Max Unit Test Conditions Resistance (Input-to-Output)1 RI-O 1012 Ω Capacitance (Input-to-Output)1 CI-O 2.0 pF f = 1 MHz Input Capacitance CI 4.0 pF IC Junction-to-Ambient Thermal Resistance θJA 76 °C/W 1 The device is considered a 2-terminal device: Pin 1 through Pin 8 are shorted together, and Pin 9 through Pin 16 are shorted together. REGULATORY INFORMATION The ADuM1234 has been approved by the organization listed in Table 3. Refer to Table 7 and the Insulation Lifetime section for details regarding recommended maximum working voltages for specific cross-isolation waveforms and insulation levels. Table 3. UL Recognized under the 1577 component recognition program1 Single/basic insulation, 2500 V rms isolation voltage 1 In accordance with UL1577, each ADuM1234 is proof tested by applying an insulation test voltage ≥ 3000 V rms for 1 second (current leakage detection limit = 5 μA).
