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、時鐘振蕩器、采樣保持器和基準電壓源(2.5 V)。AD7416僅具有溫度監(jiān)控功能，采用8引腳封裝。

通過多路復(fù)用器通道0可以訪問這些器件上的溫度傳感器。選擇通道0并啟動轉(zhuǎn)換后，轉(zhuǎn)換結(jié)束時產(chǎn)生的ADC碼為環(huán)境溫度的測量結(jié)果（25°C時精度為±1°C）?？梢詫囟鹊纳舷孪蘧幊虒懭肫瑑?nèi)寄存器，器件提供一個開漏過溫指示器(OTI)輸出；當溫度超過限值時，該輸出有效。

配置寄存器允許對OTI輸出（高電平有效或低電平有效）檢測及其工作模式（比較器或中斷）進行編程。可編程故障隊列計數(shù)器允許設(shè)置超限測量的次數(shù)，必須達到該次數(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。

由于客戶采購批量與樣品的價格不同，網(wǎng)上無法統(tǒng)一注明，請您把采購型號通過郵件或客服QQ：401799895發(fā)給我們，也可以撥打明佳達國內(nèi)銷售部電話：0755-83957301，由客服人員為您報價；有時元件廠商價格稍許變動，本公司未能及時調(diào)整，如您覺得售價稍高，請與我們說明并適當議價，感謝支持!
