    The TMP112EVM hardware consists of the SM-USB-DIG and TMP112EVM; these are easily connectable through a 10 pin board-to-board connector that should be attached to the SM-USB-DIG and TMP112EVM PCBs. Once these two boards are connected, simply plug the USB device from the SM-USB-DIG into the computer.

    The TMP112 device is a digital temperature sensor ideal for NTC/PTC thermistor replacement where high accuracy is required. The device offers an accuracy of ±0.5°C without requiring calibration or external component signal conditioning. IC temperature sensors are highly linear and do not require complex calculations or lookup tables to derive the temperature. The calibrating for improved accuracy feature allows users to calibrate for an accuracy as good as ±0.17°C (see the Calibrating for Improved Accuracy section). The on-chip 12-bit ADC offers resolutions down to 0.0625°C.
