... 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. The MAX6666/MAX6667 operate at supply voltages from +3V to +5.5V. The typical unloaded supply current at 5.0V is 200µ ...

... To calculate the temperature, use the expression below: Temperature (°C) = +235 - (400 x t The µC or µP measures the output of the MAX6666/ MAX6667 by counting t and temperature based on their ratio. The resolution of the count is a function of the processor clock frequency and the resolution of the counter ...
