TC12

The TC12 is a monolithic temperature sensor that outputs a pulse waveform whose duty cycle varies in direct proportion to measured temperature. This output format is easily converted to binary data using logic or the counter/ timer circuit on-board the system microcontroller. Typical accuracy is ±1over the rated measurement range of 40 to +125. It operates from supply voltages as low as 2.7V.

Unlike voltage output temperature sensors, the digital output of the TC12 offers superior immunity to system noise
and does not require an A/D converter. Unlike two wire serial temperature sensors, the TC12 communicates over a single wire, and without complex serial protocol overhead.
