AD7687 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 6. THERMAL RESISTANCE Parameter Rating
θJA is specified for the worst-case conditions, that is, a device Analog Inputs soldered in a circuit board for surface-mount packages. IN+1, IN−1 GND − 0.3 V to VDD + 0.3 V or ±130 mA
Table 7. Thermal Resistance
REF GND − 0.3 V to VDD + 0.3 V
Package Type θJA θJC Unit
Supply Voltages 10-Lead LFCSP 84 2.96 °C/W VDD, VIO to GND −0.3 V to +7 V 10-Lead MSOP 200 44 °C/W 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 Lead Temperature Range JEDEC J-STD-20 1 See the Analog Input section. 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. Rev.
