MAX6672 - Maxim Integrated Products

MAX6672 PWM Output Temperature Sensors

The MAX6672/MAX6673 are low-current temperature sensors with a single-wire output. These temperature sensors convert the ambient temperature into a 1.4kHz PWM output, which contains the temperature information 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 m.
