AD7818ARM-REEL規(guī)格書(shū)詳情

AD7818ARM-REEL屬于傳感器變送器的溫度傳感器-模擬數(shù)字輸出。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD7818ARM-REEL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(cè)量環(huán)境熱能量。特征包括傳感器類(lèi)型、本地感測(cè)溫度、遠(yuǎn)程感測(cè)溫度、輸出類(lèi)型、電源電壓和分辨率。傳感器類(lèi)型為模擬本地/遠(yuǎn)程/紅外、模擬數(shù)字、本地/遠(yuǎn)程、數(shù)字本地/遠(yuǎn)程/紅外或內(nèi)部,感應(yīng)溫度范圍為 -55°C 至 200°C。

GENERAL DESCRIPTION

The AD7818 and AD7817 are 10-bit, single- and 4-channel A/D converters with on-chip temperature sensor that can operate from a single 2.7 V to 5.5 V power supply. Each part contains a 9 μs successive-approximation converter based around a capacitor DAC, an on-chip temperature sensor with an accuracy of ±2°C, an on-chip clock oscillator, inherent track-and hold functionality and an on-chip reference (2.5 V). The AD7816 is a temperature monitoring only device in a SOIC/MSOP package.

The on-chip temperature sensor of the AD7817 and AD7818 can be accessed via Channel 0. When Channel 0 is selected and a conversion is initiated, the resulting ADC code at the end of the conversion gives a measurement of the ambient temperature with a resolution of ±0.25°C. See Temperature Measurement section of this data sheet.

The AD7816, AD7817, and AD7818 have a flexible serial interface that allows easy interfacing to most microcontrollers. The interface is compatible with the Intel 8051, Motorola SPI? and QSPI? protocols and National Semiconductors MICROWIRE? protocol. For more information refer to the Serial Interface section of this data sheet.

The AD7817 is available in a narrow body 0.15 16-lead small outline IC (SOIC), in a 16-lead, thin shrink small outline package (TSSOP), while the AD7816/AD7818 come in an 8-lead small outline IC (SOIC) and an 8-lead microsmall outline IC (MSOP).
