MAX6662  
12-Bit + Sign Temperature Sensor with  
SPI-Compatible Serial Interface  
General Description  
Features  
12-Bit + Sign, 0.0625°C Resolution  
The MAX6662 is a 12-bit + sign temperature sensor  
combined with a programmable overtemperature alarm  
and a 3-wire (SPI-compatible) serial interface in a single  
package. It converts its die temperature into digital values  
using an internal analog-to-digital converter (ADC). The  
temperature data is stored in a temperature register as a  
13-bit word, which allows 0.0625°C resolution. The tem-  
perature data is readable at any time through the serial  
interface. The operating temperature range is -55°C to  
+150°C.  
Accuracy  
±1°C max (+30°C to +50°C)  
±1.6°C max (0°C to +70°C)  
±2.5°C max (-20°C to +85°C)  
±2.5 typ (+150°C)  
Extended Temperature Measurement Range  
-55°C to +150°C  
Low Average Supply Current, 125µA (typ)  
Shutdown Mode to Minimize Power Consumption in  
The MAX6662 provides two programmable watchdog  
interrupt outputs. ALERT is used for lower temperature  
warning functions, while OT is used for higher tempera-  
ture-critical functions, such as power-supply shutdown.  
The MAX6662 features a shutdown mode that saves  
power by disabling everything except the serial interface.  
The temperature sensor is available in an 8-pin SO pack-  
age.
