具有集成緩沖器和使能引腳的 5V、5ppm/°C 高精度電壓基準

REF6000 系列電壓基準集成低輸出阻抗緩沖器，這使得用戶能夠直接驅(qū)動精密數(shù)據(jù)轉(zhuǎn)換器的 REF 引腳，同時維持線性度、失真和噪聲性能。多數(shù)精密 SAR 和 Δ-Σ ADC 在轉(zhuǎn)換過程中會將二進制加權(quán)電容切換到 REF 引腳。為了支持這一動態(tài)負載，必須通過一個低輸出阻抗（高帶寬）緩沖器緩沖電壓基準的輸出。REF6000 系列器件非常適合（但不限于）驅(qū)動 ADS88xx 系列 SAR ADC 和 ADS127xx 系列 Δ-Σ ADC 以及其他數(shù)模轉(zhuǎn)換器 (DAC) 的 REF 引腳。 在驅(qū)動 ADS8881 的 REF 引腳時，即使在首次轉(zhuǎn)換過程中，REF6000 系列電壓基準的輸出電壓也不會 ? 出色的溫度漂移性能 \n? 極低噪聲 \n? 1/f 噪聲（0.1Hz 至 10Hz）：3 μVPP/V \n? 集成 ADC 驅(qū)動器緩沖器 \n? 低電源電流：820μA \n? 高初始精度：±0.05%\n? 信噪比 (SNR)：100.5dB，總諧波失真 (THD)：-125dB (ADS8881)\n? 輸出電流驅(qū)動能力：±4mA\n? 經(jīng)驗證用于驅(qū)動 ADS88xx 系列逐次逼近寄存器 (SAR) ADC 和 ADS127xx 系列寬頻帶 Δ-Σ ADC 的 REF 引腳;
