AD7416

10位數(shù)字溫度傳感器; ? 片內(nèi)溫度傳感器:\n?40°C至 +125°C\n\n? 過(guò)溫指示器\n\n? 寬工作電壓范圍：2.7 V至5.5 V\n\n? I2C兼容串行接口\n\n? 可選串行總線地址，一條總線最多可以連接8個(gè)AD7416/AD7417器件\n\n? AD7416是LM75的出色替代產(chǎn)品;

AD7417和AD7418是10位、四通道和單通道ADC，具有片內(nèi)溫度傳感器，可采用2.7 V至5.5 V單電源供電。這些器件內(nèi)置15 μs逐次逼近型轉(zhuǎn)換器、5通道多路復(fù)用器、溫度傳感器、時(shí)鐘振蕩器、采樣保持器和基準(zhǔn)電壓源(2.5 V)。AD7416僅具有溫度監(jiān)控功能，采用8引腳封裝。 通過(guò)多路復(fù)用器通道0可以訪問(wèn)這些器件上的溫度傳感器。選擇通道0并啟動(dòng)轉(zhuǎn)換后，轉(zhuǎn)換結(jié)束時(shí)產(chǎn)生的ADC碼為環(huán)境溫度的測(cè)量結(jié)果（25°C時(shí)精度為±1°C）。可以將溫度的上下限編程寫(xiě)入片內(nèi)寄存器，器件提供一個(gè)開(kāi)漏過(guò)溫指示器(OTI)輸出；當(dāng)溫度超過(guò)限值時(shí)，該輸出有效。\n\n 配置寄存器允許對(duì)OTI輸出（高電平有效或低電平有效）檢測(cè)及其工作模式（比較器或中斷）進(jìn)行編程。可編程故障隊(duì)列計(jì)數(shù)器允許設(shè)置超限測(cè)量的次數(shù)，必須達(dá)到該次數(shù)才能觸發(fā)OTI輸出，從而防止高噪聲環(huán)境中的雜散現(xiàn)象觸發(fā)OTI輸出。\n\n AD7416/AD7417/AD7418的寄存器通過(guò) I2C? 兼容串行接口進(jìn)行讀寫(xiě)。AD7416/AD7417串行總線地址的3個(gè)LSB是可以選擇的，因此一條總線最多可以連接8個(gè)AD7416/AD7417器件。\n\n AD7417采用窄體、0.15英寸、16引腳小型封裝(SOIC)或16引腳超薄緊縮小型封裝(TSSOP)。AD7416和AD7418采用8引腳SOIC或MSOP封裝。\n\n產(chǎn)品聚焦\n\n AD7416/AD7417/AD7418具有片內(nèi)溫度傳感器，可以精確測(cè)量環(huán)境溫度（25°C時(shí)精度為±1°C，±2°C過(guò)溫）。測(cè)量溫度范圍為?40°C至+125°C。通過(guò)將通道0（溫度傳感器）的ADC碼與片內(nèi)TOTI設(shè)定點(diǎn)寄存器的內(nèi)容進(jìn)行比較，實(shí)現(xiàn)過(guò)溫指示功能。 AD7417是一款節(jié)省空間的10位模數(shù)轉(zhuǎn)換解決方案，具備四個(gè)外部電壓輸入通道、片內(nèi)溫度傳感器、片內(nèi)基準(zhǔn)電壓源和時(shí)鐘振蕩器。 通過(guò)自動(dòng)關(guān)斷功能，AD7416/AD7417/AD7418可實(shí)現(xiàn)出色的功耗性能。吞吐速率較低時(shí)，器件可以進(jìn)入低功耗關(guān)斷模式，進(jìn)一步降低功耗。
