Overview
The TMP03FT9 from Analog Devices Inc. is a monolithic temperature detector that provides a comprehensive temperature measurement system on a single chip. This device generates a modulated serial digital output that varies in direct proportion to the temperature of the device. It features an onboard temperature sensor that produces a voltage precisely proportional to absolute temperature, which is then digitized by a first-order sigma-delta modulator. This results in a highly accurate and linear temperature measurement without the need for user calibration or correction.
