概述

Description

TMP103AYFFT is a Texas Instruments digital temperature sensor (TMP103 family) with an I2C interface. It provides a digital temperature reading from a 12‑bit conversion (0.0625°C per LSB) and operates on a single supply (typically 2.7–5.5 V). It offers low power consumption and is suitable for microcontroller-based temperature monitoring in general-purpose and industrial applications. The AYFFT suffix denotes the specific package/grade variant; exact pinout, timing, and electrical specs are in the TMP103 datasheet and product page.

Features

TMP103AYFFT is a digital temperature sensor with I2C output. Key features:
- I2C/SMBus-compatible 2‑wire digital interface
- 12‑bit temperature conversion with 0.0625°C per LSB
- Wide operating range: -40°C to +125°C
- Supply voltage: 2.7 V to 5.5 V
- Typical accuracy around ±0.5°C over much of the range
- Low power with multiple modes (continuous, one-shot, and shutdown)
- Programmable alert/interrupt output with comparator/interrupt modes
- Small 8-pin package (e.g., MSOP/VSSOP) suitable for compact designs
Note: Check the specific datasheet for exact accuracy, package variant, and addressing details.

Package
