VDD to GND −0.3 V to +7 V Low 1001 000 Analog Input Voltage to GND −0.3 V to VDD + 0.3 V Float 1001 010 Digital Input Voltage to GND −0.3 V to VDD + 0.3 V High 1001 011 Operating Temperature Range −40°C to +120°C Stresses at or above those listed under Absolute Maximum Storage Temperature Range −65°C to +150°C Ratings may cause permanent damage to the product. This is a Junction Temperature stress rating only; functional operation of the product at these 16-Lead QSOP 150°C or any other conditions above those indicated in the operational Power Dissipation1 (TJmax − TA)/θJA section of this specification is not implied. Operation beyond Thermal Impedance2 the maximum operating conditions for extended periods may θJA Junction-to-Ambient 105.44°C/W affect product reliability. θJC Junction-to-Case 38.8°C/W IR Reflow Soldering

Peak Temperature 220°C (0°C/5°C) Time at Peak Temperature 10 sec to 20 sec Ramp-Up Rate 2°C/sec to 3°C/sec Ramp-Down Rate −6°C/sec IR Reflow Soldering (Pb-Free Package) Peak Temperature 260°C (+0°C) Time at Peak Temperature 20 sec to 40 sec Ramp-Up Rate 3°C/sec maximum Ramp-Down Rate −6°C/sec maximum Time 25°C to Peak Temperature 8 minutes maximum 1 Values relate to package being used on a 4-layer board. 2 Junction-to-case resistance is applicable to components featuring a preferential flow direction, for example, components mounted on a heat sink. Junction-to-ambient resistance is more useful for air-cooled PCB- mounted components. Rev.
