REF35超低功耗高精度電壓基準(zhǔn)是毫微功耗、低漂移、高精度參考器件，初始精度高達(dá)±0.05%，功耗通常低于700nA,低溫漂移 (10ppm/°C) 和長期漂移（20ppm，1000小時）確保系統(tǒng)穩(wěn)定性和可靠性。REF35超低功耗精密電壓基準(zhǔn)的工作溫度范圍為-40°C至+125°C，在-55°C至+125°C寬溫度范圍內(nèi)可以正常工作，因此適合用于工業(yè)應(yīng)用。REF35元件具有低功耗和高精度規(guī)格，因此可用于各種便攜式和低電流應(yīng)用。
|
|
REF35提供高達(dá)10mA電流，具有8.5ppmp-p噪聲和30ppm/mA負(fù)載調(diào)節(jié)能力,憑借這些特性，REF35可為精密傳感器和12-16b數(shù)據(jù)轉(zhuǎn)換器提供強(qiáng)大的低噪聲、高精度電源且具有1.024V至5.0V寬輸出電壓范圍，采用節(jié)省空間的SOT23 6引腳封裝。
