Digital Thermometer and Thermostat  
General Description  
Features  
The DS7505 low-voltage (1.7V to 3.7V) digital ther-  
mometer and thermostat provides 9-, 10-, 11-, or 12-bit  
digital temperature readings over a -55°C to +125°C  
range with 0.5°C accuracy over a -0°C to +70°C range.  
A 9-bit resolution mode is software compatible with the  
LM75. Communication with the DS7505 is achieved  
through a simple 2-wire serial interface. Three address  
pins allow up to eight DS7505 devices to operate on the  
same 2-wire bus, which greatly simplifies distributed  
temperature-sensing applications.  
o Operating Range from 1.7V to 3.7V  
o Temperature Measurements Require No External  
Components  
o Measures Temperatures from -55°C to +125°C  
(-67°F to +257°F)  
o
0.5°C Accuracy Over a 0°C to +70°C Range  
o Thermometer Resolution is User-Configurable  
from 9 (Default) to 12 Bits (0.5°C to 0.0625°C  
Resolution)  
The DS7505 thermostat has a dedicated open-drain out-  
put (O.S.) and programmable fault tolerance, which  
allows the user to define the number of consecutive  
error conditions that must occur before O.S. is activated.  
There are two thermostatic operating modes that control  
thermostat operation based on user-defined trip points  
o 9-Bit Conversion Time is 25ms (max)  
o Thermostatic Settings are User-Definable and  
Nonvolatile (NV)  
o Stand-Alone Thermostat Capability  
(T and T  
) that are stored in EEPROM registers.
