TCN75AVOA屬于傳感器變送器的溫度傳感器-模擬數(shù)字輸出。由微芯科技股份有限公司制造生產(chǎn)的TCN75AVOA溫度傳感器 - 模擬和數(shù)字輸出模擬和數(shù)字輸出溫度傳感器可用于測量環(huán)境熱能量。特征包括傳感器類型、本地感測溫度、遠程感測溫度、輸出類型、電源電壓和分辨率。傳感器類型為模擬本地/遠程/紅外、模擬數(shù)字、本地/遠程、數(shù)字本地/遠程/紅外或內(nèi)部，感應(yīng)溫度范圍為 -55°C 至 200°C。

Description:

Microchip Technology Inc.’s TCN75A digital temperature sensor converts temperatures between -40°C and +125°C to a digital word, with ±1°C (typ.) accuracy.

The TCN75A product comes with user-programmable registers that provide flexibility for temperature-sensing applications. The register settings allow user-selectable, 0.5°C to 0.0625°C temperature measurement resolution, configuration of the power-saving Shutdown and One-shot (single conversion on command while in Shutdown) modes and the specification of both temperature alert output and hysteresis limits. When the temperature changes beyond the specified limits, the TCN75A outputs an alert signal. The user has the option of setting the alert output signal polarity as an active-low or active-high comparator output for thermo stat operation, or as temperature event interrupt output for microprocessor-based systems.
