數(shù)據(jù): TMP461 具有引腳可編程的總線地址的高精度遠程和本地溫度傳感器 數(shù)據(jù)表 (Rev. B)
這個遠程溫度傳感器通常采用低成本分立式NPN或PNP晶體管,或者基板熱晶體管或二極管,這些器件都是微處理器,微控制器或現(xiàn)場可編程門陣列(FPGA)的組成部件。本地和遠程傳感器均用12位數(shù)字編碼表示溫度,分辨率為0.0625°C。此兩線制串口接受SMBus通信協(xié)議,以及多達9個不同的引腳可編程地址。
該器件將諸如串聯(lián)電阻抵消,可編程非理想性因子(η因子),可編程偏移,可編程溫度限制和可編程數(shù)字濾波器等高級特性完美結(jié)合,提供了一套準(zhǔn)確度和抗擾度更高且穩(wěn)健耐用的溫度監(jiān)控解決方案。
TMP461非常適合各類通信,計算,儀器儀表和工業(yè)應(yīng)用中的多位置,高精度溫度測量。該器件的額定電源電壓范圍為1.7V至3.6 V,額定工作溫度范圍為-40°C至125°C。
