General Description

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 temperature 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.
