ADR292

低噪聲、微功耗、精密基準(zhǔn)電壓源(4.096 V); ? 電源電壓范圍 \n2.8 V至15 V (ADR291)\n4.4 V至15 V (ADR292)\n\n? 電源電流：15 μA（最大值）\n\n? 低噪聲：8 μV和12 μV峰峰值 (0.1 Hz 至 10 Hz);

ADR291和ADR292均為低噪聲、微功耗、精密基準(zhǔn)電壓源，采用XFET?基準(zhǔn)電壓源電路。與傳統(tǒng)的帶隙和嵌入式齊納二極管基準(zhǔn)電壓源相比，全新的XFET架構(gòu)在性能方面有明顯改進(jìn)。具體包括：工作電流相同時，電壓噪聲輸出僅為帶隙基準(zhǔn)電壓源的1/4；極低的超線性溫度漂移；低熱滯特性；以及出色的長期穩(wěn)定性。\n\n ADR291/ADR292系列基準(zhǔn)電壓源可提供穩(wěn)定、精確的輸出電壓，ADR291的電源電壓可低至2.8 V。ADR291和ADR292的輸出電壓分別為2.5 V和4.096 V。\n\n 靜態(tài)電流僅為12 μA，因此這些器件是電池供電儀器儀表的理想選擇。ADR291和ARD292各提供三種電氣等級產(chǎn)品，其初始輸出精度分別為±2 mV、±3 mV、±6 mV（最大值，ADR291），以及±3 mV、±4 mV、±6 mV（最大值，ADR292）。三種等級產(chǎn)品的溫度系數(shù)分別為8 ppm/°C、15 ppm/°C和25 ppm/°C（最大值）。電壓調(diào)整率和負(fù)載調(diào)整率分別為30 ppm/V和30 ppm/mA（典型值），有利于保持基準(zhǔn)電壓源的整體高性能水平。如需5.0 V輸出器件，請參考ADR293數(shù)據(jù)手冊。\n\n ADR291和ADR292的額定溫度范圍為?40°C至+125°C擴(kuò)展工業(yè)溫度范圍，提供8引腳SOIC、8引腳TSSOP和3引腳TO-92三種封裝。 \n\nul { margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:15px; padding-top:0px; padding-right:0px; padding-bottom:10px; padding-left:0px;}li { padding-top:0px; padding-right:0px; padding-bottom:5px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px;}
