2 / 9 page  12-Bit + Sign Temperature Sensor with SPI-Compatible Serial Interface 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VCC = +3V to +5.5V, TA = -55°C to +125°C, unless otherwise noted. Typical values are at TA = +25°C and VCC = +3.3V.) 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. All Voltages Are Referenced to GND VCC ...........................................................................-0.3V to +6V ALERT, OT................................................................-0.3V to +6V SIO, SCLK, CS............................................-0.3V to (VCC + 0.3V) SIO Current .......................................................-10mA to +50mA Continuous Current into Any Pin (except NC)….................10mA Continuous Power Dissipation (TA = +70°C) 8-Pin SO (derate 5.9mW/°C above +70°C)..................471mW Operating Temperature Range (Note 1) ..........-55°C to +150°C Junction Temperature ......................................................+150°C Storage Temperature Range .............................-65°C to +150°C Lead Temperature (soldering, 10s) .................................+300°C Note 1: The MAX6662 is not recommended to operate above +125°C for an extended period of time.
