3. 丢脉冲电压 (VDO) 是输入到X60003x-50 的最小电压 (VIN) ,这一电压将产生输出电压降 (ΔVOUT) , 如电气指标表中所规定的值。 4.由器件的特征保证。
纳功率工作
当持续加电,且达到初始稳定工作后,基准器件达到最高精度。通过保持持续通电,可消除漂移。 X60003x-50 是第一个具有超低功耗的高精度电压基准,因此在电池供电电路中,可保持持续的供电。 由于它拥有 FGA 技术,X60003x-50 消耗极低的电源电流。室温下,电流的典型值是 500nA ,这比同类产 品低 1-2 个级别。使用电池供电的应用电路将大大得益于拥有一个精确,稳定的基准而根本不会增加电池 的负载。 特别地,在电池供电电路中,通常数据转换器在不使用时要求数据转换器(如图 1)被禁止。由于极 低的功耗,基准器件保持供电,没有功率损失,能够提供高精度和最低的长期漂移,这样数据转换器提供 12 到 24 比特的精度。 其他基准器件因为要消耗较高的电源电流,因此在转换结束后需要停用,来降低能耗。上电后器件需 要时间调整它的最终值,很可能因为上电时间太短而没有调整最终值,使绝对精度受损失。

电压基准芯片参数以及应用技巧分析

电压基准芯片参数以及应用技巧分析

电压基准芯片参数以及应用技巧分析
电压基准芯片是一类高性能模拟芯片,常用在各种数据采集系统中,实现高精度数据采集。

几乎所有电压基准芯片都在为实现高精度而努力,但要在各种不同应用场合真正实现高精度,则需要了解电压基准的内部结构以及各项参数的涵义,并要把握一些必要的应用技巧。

电压基准芯片的分类
根据内部基准电压产生结构不同,电压基准分为:带隙电压基准和稳压管电压基准两类。

带隙电压基准结构是将一个正向偏置PN结和一个与VT(热电势) 相关的电压串联,利用PN结的负温度系数与VT的正温度系数相抵消实现温
度补偿。

稳压管电压基准结构是将一个次表面击穿的稳压管和一个PN结串联,利用稳压管的正温度系数和PN结的负温度系数相抵消实现温度补偿。

次表面击穿有利于降低噪声。

稳压管电压基准的基准电压较高(约7V);而带隙电压基准的基准电压比较低,因此后者在要求低供电电压的情况下应用更为广泛。

根据外部应用结构不同,电压基准分为:串联型和并联型两类。

应用时,串联型电压基准与三端稳压电源类似,基准电压与负载串联;并联型电压基准与稳压管类似,基准电压与负载并联。

带隙电压基准和稳压管电压基准都可以应用到这两种结构中。

串联型电压基准的优点在于,只要求输进电源提供芯片的静态电流,并在负载存在时提供负载电流;并联型电压基准则要求所设置的偏置电流大于芯片的静态电流与最大负载电流的总和,不适合低功耗应用。

并联型电压基准的优点在于,采用电流偏置,能够满足很宽的输进电压范围,而且适合做悬浮式的电压基准。
