The NXP PCT2075 is a temperature to digital converter featuring ±1 °C accuracy over ‑25 °C to +100 °C range. It uses an on chip band gap temperature sensor and Sigma Delta A‑to‑D conversion technique with an over temperature detection output that is a drop in replacement for other LM75 series thermal sensors.
