Overview
The TMP20AIDCKT is a precision analog output temperature sensor produced by Texas Instruments. This device is part of the TMP20 series and is available in compact 5-lead SC70 or 6-lead SOT-563 packages, which significantly reduce the required board space. The TMP20 operates over a wide temperature range of –55°C to +130°C and is powered by a supply voltage of 2.7 V to 5.5 V, with the ability to operate as low as 1.8 V for temperatures between 15°C and 130°C. It features a linear transfer function with a slope of –11.77 mV/°C and an output voltage of 1.8639 V at 0°C, ensuring accurate temperature measurements with a ±2.5°C accuracy across the entire specified temperature range.
