说明
The TMP275 is a 0.5°C accurate, Two-Wire, serial output temperature sensor available in an MSOP-8 or an SO-8 package. The TMP275 is capable of reading temperatures with a resolution of 0.0625°C.
The TMP275 is SMBus-compatible and allows up to eight devices on one bus. It is ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
The TMP275 is specified for operation over a temperature range of -40°C to +125°C.

特性
    * EIGHT ADDRESSES
    * DIGITAL OUTPUT: Two-Wire Serial Interface
    * RESOLUTION: 9- to 12-Bits, User-Selectable

The TMP275 is specified for operation over a temperature range of -40°C to +125°C. ACCURACY: ±0.5°C (max) from 20°C to +100°C 请问20°C以下精度是多少？

汗，原来是ACCURACY: ±0.5°C (max) from -20°C to +100°C。楼主把负号给吃了。

很明显，功耗低，有效检测温度范围内精度保证。毕竟一分价一分货。

好东西，我收了
