VDD, VIO to GND −0.3 V to +7 V 10-Lead MSOP 200 44 °C/W VDD to VIO ±7 V 10-Lead LFCSP 43.4 6.5 °C/W Digital Inputs to GND −0.3 V to VIO + 0.3 V Digital Outputs to GND −0.3 V to VIO + 0.3 V Storage Temperature Range −65°C to +150°C
ESD CAUTION
Junction Temperature 150°C Lead Temperature Range JEDEC J-STD-20 1 See the Analog Inputs 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.
