7 / 28 page AD7834/AD7835 Rev. D | Page 7 of 28 ABSOLUTE MAXIMUM RATINGS TA = 25°C unless otherwise noted. Transient currents of up to 100 mA do not cause SCR latch-up. VCC must not exceed VDD by more than 0.3 V. If it is possible for this to happen during power supply sequencing, the diode protection scheme shown in Figure 5 can be used to provide protection. Table 5. AD7834/ AD7835 VDD VCC IN4148 SD103C VDD VCC Parameter Rating VCC to DGND −0.3 V to +7 V, or VDD + 0.3 V (whichever is lower) VDD to AGND −0.3 V to +17 V VSS to AGND +0.3 V to –17 V Figure 5. Diode Protection AGND to DGND −0.3 V to +0.3 V −0.3 V to VCC + 0.3 V Digital Inputs to DGND THERMAL RESISTANCE VREF(+) to VREF(–) −0.3 V to +18 V θJA is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. VREF(+) to AGND VSS – 0.3 V to VDD + 0.3 V VREF(–) to AGND VSS – 0.3 V to VDD + 0.3 V VSS – 0.3 V to VDD + 0.3 V DSG to AGND Table 6. Thermal Resistance VOUT (1–4) to AGND VSS – 0.3 V to VDD + 0.3 V Package Type θJA Unit Operating Temperature Range, TA PDIP 75 °C/W −40°C to +85°C Industrial (A Version) SOIC 75 °C/W −65°C to +150°C Storage Temperature Range MQFP 95 °C/W 150°C Junction Temperature, TJ (max) PLCC 55 °C/W Power Dissipation, PD (max) (TJ − TA)/θJA Lead Temperature JEDEC Industry Standard ESD CAUTION Soldering J-STD-020 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. |
