SD5003 is a highly accurate temperature measurement IC with digital PWM output. An internal sensor produces a voltage signal that is proportional to temperature. It is then digitized by a built-in ADC, and modulated into a PWM waveform. The typical error is ± 0.8℃ for the -40~+100℃ range, and ±1.0℃ for the -55~+125℃ range.
Output pin DOUT is open drain which facilitates multi-voltage system applications.
