摘要： 温度特性的数字电位器有别传统机械电位器。设计使用这些类型的设备，因为数字电位器具有绝对的阻力，温度过 10%的数量级可能会有所不同时，必须考虑对电位差计的绝对电阻温度的影响。其它考虑因素，尤其是抵抗"刮"这是在现实中传输门，还必须考虑采取与这些部件设计时。给出的设计在不同的配置中的稳定性概述。如果刮水器阻力也有解释的影响。Maxim > App Notes > COMMUNICATIONS CIRCUITS DIGITAL POTENTIOMETERS FIBER-OPTIC CIRCUITS Keywords: digital pot, digitpot, epot, DS1845, DS1855, xicor, digital potemtiometers Jun 07, 2002 APPLICATION NOTE 207 DS1845/DS1855 Temperature Coefficient Analysis Abstract: The temperature characteristics of digital potentiometers differ from those of traditional mechanical potentiometers. The effects of temperature on the absolute resistance of the potentiometer must be taken into consideration when designing with these types of devices as a digital potentiometer has an absolute resistance, which might vary on an order of magnitude of 10% over temperature. Other considerations, especially the resistance of the "wiper" which is in actuality a transmission gate,……
