10 / 41 page ![]() ADE7912/ADE7913 Data Sheet Rev. C | Page 10 of 41 ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted. Table 6. Parameter Rating VDD to GND −0.3 V to +3.7 V Analog Input Voltage to GNDISO, IP, IM, V1P, V2P, VM −2 V to +2 V Reference Input Voltage to GNDISO −0.3 V to VDD + 0.3 V Digital Input Voltage to GND −0.3 V to VDD + 0.3 V Digital Output Voltage to GND −0.3 V to VDD + 0.3 V Common-Mode Transients1 −100 kV/µs to +100 kV/µs Operating Temperature Industrial Range −40°C to +85°C Storage Temperature Range −65°C to +150°C Lead Temperature (Soldering, 10 sec)2 260°C 1 Refers to common-mode transients across the insulation barrier. Common- mode transients exceeding the absolute maximum ratings may cause latch- up or permanent damage. 2 Analog Devices recommends that reflow profiles used in soldering RoHS compliant devices conform to J-STD-020D.1 from JEDEC. Refer to JEDEC for the latest revision of this standard. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. THERMAL RESISTANCE θJA and θJC are specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. Table 7. Thermal Resistance Package Type θJA θJC Unit 20-Lead SOIC_IC 48.0 6.2 °C/W ESD CAUTION Table 8. Maximum Continuous Working Voltage Supporting a 50-Year Minimum Lifetime1 Parameter Max Unit AC Voltage, Bipolar Waveform 400 V rms DC Voltage, Basic Insulation 1173 V peak 1 Refers to the continuous voltage magnitude imposed across the isolation barrier. See the Insulation Lifetime section for more details. Note that greater working voltages than the values presented in Table 8 shorten the lifetime of the product (see the Insulation Lifetime section). Therefore, although some certifications in Table 2 state bigger maximum working voltages, use the ADE7912/ADE7913 only for working voltages lower than the values presented in this Table 8. |
