This document is a product manual for TC1047/TC1047A, which introduces its features, characteristics and applications.
The TC1047 and TC1047A are linear voltage‑output temperature sensors that convert temperature to a proportional voltage. They operate from –40 °C to +125 °C and are supplied in a 3‑Pin SOT‑23B package, making them suitable for space‑critical applications. Supply voltage ranges are 2.7 V‑4.4 V for the TC1047 and 2.5 V‑5.5 V for the TC1047A, with a typical supply current of only a few tens of picoamps.
Key specifications include a fixed 10 mV/°C slope, 500 mV output at 0 °C, and accuracy of ±2 °C at 25 °C. The datasheet also details pin functions, mechanical dimensions, and typical performance curves, along with revision history and code‑protection notices.
