3V Vref、低温漂、低功耗、双输出 Vref 和 Vref/2 电压基准

仅具有 正向电源电压的应用通常需要一个在模数转换器 (ADC) 输入范围中间位置的附加稳定电压来偏置输入双极信号。REF20xx 提供了一个可供 ADC 使用的基准电压 (VREF) 和一个可用于偏置输入双极信号的高精度电压 (VBIAS)。\n\nREF20xx 在 VREF 和 VBIAS 输出端具有优异的温度漂移（最大 8 ppm/°C）特性和初始精度 (0.05%)，同时可保持静态工作电流低于 430µA。此外，VREF 和 VBIAS 输出端可在 –40°C 至 85°C 的温度范围内彼此跟踪，精度达 6 ppm/°C（最大值）。所有这些 特性 都可提高信号链的精度并节省电路 • 两个输出：VREF 和 VREF/2，便于在单电源系统中使用\n• 优异的温度漂移性能： \n• -40℃ 至 125℃ 时为 8 ppm/°C（最大值）\n \n• 高初始精度：±0.05%（最大值）\n• 温度范围内的 VREF 和 VBIAS 跟踪： \n• -40℃ 至 85℃ 时为 6 ppm/°C（最大值）\n• -40℃ 至 125℃ 时为 7 ppm/°C（最大值）\n \n• 微型封装：SOT23-5\n• 低压降电压：10mV\n• 高输出电流：±20mA\n• 低静态电流：360µA\n• 线路调节：3 ppm/V \n• 负载调节：8 ppm/mA\n• M;
