... These temperature sensors convert the ambient temperature into a 1.4kHz PWM output, which contains the temperature informa- tion in its duty cycle. The MAX6672 has an open-drain output and the MAX6673 has a push-pull output. The MAX6672/MAX6673 operate from 2.4V to 5.5V with a maximum supply current of 150µA. Both devices fea- ture a single-wire output that minimizes the number of pins necessary to interface with a microprocessor ...

... As with any IC, the wiring and circuits must be kept insulated and dry to avoid leakage and corrosion, especially if the part is operated at cold temperatures where condensation can occur. The error caused by power dissipation in the MAX6672/ MAX6673 is negligible. TRANSISTOR COUNT: 601 PROCESS: BiCMOS in SC70 Packages ...
