ADR42x系列為超精密、第二代外加離子注入場效應(yīng)管(XFET)基準(zhǔn)電壓源，具有低噪聲、高精度和出色的長期穩(wěn)定特性，采用SOIC和MSOP封裝。\n\n 利用溫度漂移曲率校正專利技術(shù)和XFET技術(shù)，可以使電壓隨溫度變化的非線性度降至較小。XFET架構(gòu)能夠為帶隙基準(zhǔn)電壓源提供出色的精度和熱滯性能。與嵌入式齊納二極管基準(zhǔn)電壓源相比，還能以更低的功耗和更小的電源裕量工作。\n\n ADR42x具有出色的噪聲性能、穩(wěn)定性和精度，非常適合光纖網(wǎng)絡(luò)和醫(yī)療設(shè)備等精密轉(zhuǎn)換應(yīng)用。此外還可利用其調(diào)整引腳，在±0.5%范圍內(nèi)調(diào)整輸出電壓，其它性能則不受影響。ADR42x系列分為兩種電氣等級，額定溫度范圍為?40°C至+125°C擴(kuò)展工業(yè)溫度范圍，提供8引腳SOIC封裝或8引腳MSOP封裝（后者比前者小30%）。\n\n
