MAX6627/MAX6628 Remote ±1°C Accurate Digital Temperature Sensors with SPI-Compatible Serial Interface
Absolute Maximum Ratings
(All voltages referenced to GND.) Continuous Power Dissipation (TA = +70°C) VCC ..-0.3V to +6V SOT23 (derate 9.7mW/°C above +70°C) ..777mW SDO, SCK, DXP, CS .. -0.3V to (VCC + 0.3V) TDFN (derate 18.5mW/°C above +70°C) ...1481.5mW DXN ..-0.3V to +0.8V Operating Temperature Range ... -55°C to +125°C SDO Pin Current Range ... -1mA to +50mA Junction Temperature ..+150°C Current Into All Other Pins ...10mA Storage Temperature Range .. -65°C to +150°C ESD Protection (Human Body Model)...±2000V Lead Temperature (soldering, 10s) ...+300°C Soldering Temperature (reflow) ...+260°C Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
