REF34-Q1 器件是低温漂 (6ppm/°C)、低功耗、高精度 CMOS 电压基准。该器件具有 ±0.05% 初始精度、低运行电流以及小于 95µA 的功耗,还提供 3.8µVPP/V 的极低输出噪声,这使得器件在用于高分辨率数据转换器和噪声关键型系统时能够保持高信号完整性。
这些器件的低输出电压迟滞和低长期输出电压漂移进一步提高了稳定性和系统可靠性。此外,此类器件的小尺寸和低运行电流 (95µA) 使其非常适合电池供电类应用。REF34-Q1 具有一个可将器件设置为关断模式的使能引脚,在该模式下,器件消耗低待机电流 (3µA),有助于降低待机期间的总体系统功耗。
REF34-Q1 系列具有 −40°C 至 +125°C 的宽额定温度范围。有关其他电压选项,请联系 TI 销售代表。
