Overview
The TMP01ESZ, produced by Analog Devices Inc., is a low-power, programmable temperature controller and sensor. This device generates a voltage output proportional to absolute temperature and provides control signals when the temperature exceeds or falls below user-set thresholds. The TMP01ESZ utilizes proprietary thin-film resistors and production laser trimming to achieve a temperature accuracy of ±1°C (typical) over the rated temperature range, ensuring excellent linearity.
