8 / 32 page AD7938/AD7939 Preliminary Technical Data ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted. Table 4. Parameter Rating VDD to AGND/DGND −0.3 V to +7 V VDRIVE to AGND/DGND −0.3 V to VDD +0.3 V Analog Input Voltage to AGND −0.3 V to VDD + 0.3 V Digital Input Voltage to DGND −0.3 V to 7 V VDRIVE to VDD −0.3 V to VDD + 0.3 V Digital Output Voltage to DGND −0.3 V to VDRIVE + 0.3 V VREFIN to AGND −0.3 V to VDD + 0.3 V AGND to DGND −0.3 V to + 0.3 V Input Current to Any Pin Except Supplies1 ±10 mA Operating Temperature Range Commercial (B Version) −40°C to +85°C Storage Temperature Range −65°C to +150°C Junction Temperature 150°C θJA Thermal Impedance 108.2°C/W (LFCSP) 121°C/W (TQFP) θJC Thermal Impedance 32.71°C/W (LFCSP) 45°C/W (TQFP) Lead Temperature, Soldering Reflow Temperature (10 sec to 30 sec) 255°C ESD 2 kV 1 Transient currents of up to 100 mA will not cause SCR latch-up. 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 listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev. PrN | Page 8 of 32 |
