3V Vref、雙輸出 Vref 和 Vref/2 電壓基準(zhǔn)

僅具有 正向電源電壓的應(yīng)用通常需要一個(gè)在模數(shù)轉(zhuǎn)換器 (ADC) 輸入范圍中間位置的附加穩(wěn)定電壓來偏置輸入雙極信號(hào)。REF19xx 提供了一個(gè)可供 ADC 使用的基準(zhǔn)電壓 (VREF) 和一個(gè)可用于偏置輸入雙極信號(hào)的高精度電壓 (VBIAS)。\n\nREF19xx 在 VREF 和 VBIAS 輸出端具有優(yōu)異的溫度漂移（最大 25 ppm/°C）特性和初始精度 (0.1%)，同時(shí)可保持靜態(tài)電流低于 430μA。此外，VREF 和 VBIAS 輸出端可在 –40°C 至 85°C 的溫度范圍內(nèi)彼此跟蹤，精度達(dá) 6 ppm/°C（最大值）。所有這些 特性 都可提高信號(hào)鏈的精度并節(jié)省電路板空 ? 兩個(gè)輸出，VREF 和 VREF/2，便于在單電源系統(tǒng)中使用\n? 出色的溫度漂移性能： \n? -40℃ 至 125℃ 時(shí)為 25 ppm/°C（最大值）\n \n? 高初始精度：±0.1%（最大值）\n? 溫度范圍內(nèi)的 VREF 和 VBIAS 跟蹤： \n? -40℃ 至 85℃ 時(shí)為 6 ppm/°C（最大值）\n? -40℃ 至 125℃ 時(shí)為 7 ppm/°C（最大值）\n \n? 微型封裝：SOT23-5\n? 低壓降電壓：10mV\n? 高輸出電流：±20mA\n? 低靜態(tài)電流：360μA\n? 線路調(diào)節(jié)：3 ppm/V \n? 負(fù)載調(diào)節(jié)：8 ppm/mA;
