AD7693 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 5. Parameter Rating
Stresses above those listed under Absolute Maximum Ratings Analog Inputs may cause permanent damage to the device. This is a stress IN+,1 IN−1 GND − 0.3 V to VDD + 0.3 V rating only; functional operation of the device at these or any or ±130 mA other conditions above those indicated in the operational REF GND − 0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute Supply Voltages maximum rating conditions for extended periods may affect VDD, VIO to GND −0.3 V to +7 V device reliability. VDD to VIO ±7 V Digital Inputs to GND −0.3 V to VIO + 0.3 V
ESD CAUTION
Digital Outputs to GND −0.3 V to VIO + 0.3 V Storage Temperature Range −65°C to +150°C Junction Temperature 150°C θJA Thermal Impedance (MSOP-10) 200°C/W θJC Thermal Impedance (MSOP-10) 44°C/W Lead Temperature Range JEDEC J-STD-20 1 See the Analog Inputs section.
