Long Twisted Pair Reads Digital Temperature Sensor


Abstract:This circuit is a simple and economical interface for remote IC thermal sensors. The temperature sensor (MAX6576), an
absolute temperature-to-period converter that integrates the sensor with the necessary signal electronics, connects to the
receiver (a MAX9140 comparator) using a twisted-pair cable that carries power to and signals from the sensor.
