ABSOLUTE MAXIMUM RATINGS
All Voltages Are Referenced to GND
V
ALERT, OT................................................................-0.3V to +6V
SIO, SCLK, CS............................................-0.3V to (V
SIO Current .......................................................-10mA to +50mA
Continuous Current into Any Pin (except NC)….................10mA
12-Bit + Sign Temperature Sensor with
SPI-Compatible Serial Interface
Note 1: The MAX6662 is not recommended to operate above +125°C for an extended period of time.
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.
