High-Accuracy PWM Output Temperature  
Sensors  
General Description  
Features  
The MAX6666/MAX6667 are high-accuracy, low-cost,  
low-power temperature sensors with a single-wire  
output. The MAX6666/MAX6667 convert the ambient  
temperature into a ratiometric PWM output with temper-  
ature information contained in the duty cycle of the out-  
put square wave. The MAX6666 has a push-pull output  
and the MAX6667 has an open-drain output.  
o Simple Single-Wire PWM Output  
o ±±1.0° ꢀAAurꢁAc ꢁt ꢂ+20°  
o High ꢀAAurꢁAc  
±±0° ꢁt ꢃ = ꢂ3.0°  
±+120° ꢁt ꢃ = ꢂ±.0° to ꢂ2.0°  
o Operꢁte Up to ꢂ±+20°  
The MAX6666/MAX6667 operate at supply voltages  
from +3V to +5.5V. The typical unloaded supply current  
at 5.0V is 200µA. Both devices feature a single-wire  
output that minimizes the number of pins necessary to  
interface with a microprocessor (µP). The output is a  
square wave with a nominal frequency of 35Hz ( 20ꢀ)  
at +25°C. The output format is decoded as follows:

MAX6666/MAX6667 operate from -40°C to +125°C and are  
available in space-saving SOT23 and µMAX packages.
