12-Bit + Sign Digital Temperature Sensors  
with Serial Interface  
9–MAX632  
General Description  
Features  
The MAX6629–MAX6632 are local digital temperature  
sensors with an SPI™-compatible serial interface. The  
temperature is converted to a 12-bit + sign word with a  
resolution of 0.0625°C/LSB. An extended temperature  
range provides useful readings up to +150°C.  
Low Power Consumption  
32µA typ (MAX6631/MAX6632)  
200µA typ (MAX6629/MAX6630)  
12-Bit + Sign Resolution with 0.0625°C/LSB  
These sensors are 3-wire serial interface SPI compati-  
ble, allowing the MAX6629–MAX6632 to be readily con-  
nected to a variety of microcontrollers (µCs). The  
MAX6629–MAX6632 are read-only devices, simplifying  
their use in systems where only temperature data is  
required.  
Accuracy  
1°C (max) from 0°C to +70°C  
+150°C Extended Temperature Range  
SPI-Compatible Serial Interface  
+3.0V to +5.5V Supply Range  
6-Pin TDFN and SOT23 Packages  
Lead-Free Version Available (TDFN Package)  
All four digital temperature sensors require very little  
supply current, making them ideal for portable systems.  
The MAX6631/MAX6632 perform a temperature-to-digi-  
tal conversion once every 8s and require minimal aver-  
age supply current, 32µA (typ). The MAX6629/  
MAX6630 perform a conversion once every 0.5s and  
require only 200µA (typ) supply current. Any of these  
temperature sensors can perform conversions more  
often—up to approximately four conversions per sec-  
ond by reading the conversion results more often.
