RM-10 147 38 °C/W Supply Voltage CP-10-9 114 33 °C/W REF, VIO to GND −0.3 V to +6.0 V VDD to GND −0.3 V to +2.1 V 1 Test Condition 1: thermal impedance simulated values are based upon use VDD to VIO −6 V to +2.4 V of 2S2P JEDEC PCB. See the Ordering Guide. 2 θ Digital Inputs to GND −0.3 V to VIO + 0.3 V JA is the natural convection junction-to-ambient thermal resistance measured in a one cubic foot sealed enclosure. Digital Outputs to GND −0.3 V to VIO + 0.3 V 3 θJC is the junction-to-case thermal resistance. Storage Temperature Range −65°C to +150°C Junction Temperature 150°C
ESD CAUTION
Lead Temperature Soldering 260°C reflow as per JEDEC J-STD-020 ESD Ratings Human Body Model 4 kV Machine Model 200 V Field Induced Charged Device Model 1.25 kV 1 See the Analog Inputs section for an explanation of IN+ and IN−. 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.
