Overview
The TMP01FSZ, produced by Analog Devices Inc., is a low-power, programmable temperature controller and sensor. It combines a band gap voltage reference with a pair of matched comparators to provide both a constant 2.5 V output and a voltage proportional to absolute temperature (VPTAT). The VPTAT has a precise temperature coefficient of 5 mV/K and is 1.49 V (nominal) at 25°C. This device is designed for high accuracy and reliability, utilizing proprietary thin-film resistors and production laser trimming to maintain a temperature accuracy of ±1°C (typical) over the rated temperature range.
