摘要： DS1869是一个64位数字电位器与“向上/向下”的控制，这使得机械式电位器类似的方式调整。该器件具有三种操作模式，允许从一个单一的按钮控制，双按钮，或从一个微处理器或微控制器控制，硬成电路芯片是如何而定。上电时，电位器的“感觉”的配置，并切换到适当的操作模式。配置是至关重要的，因为它是可以尝试配置该设备为一体的经营模式，但实际上强行进入错误模式。本应用笔记详细配置的细节，以避免这类应用问题。Maxim > Design Support > App Notes > Digital Potentiometers > APP 168 Maxim > Design Support > App Notes > General Engineering Topics > APP 168 Keywords: digital potentiometers, digital pot, xicor, DS1669, DS1869, digipot Jan 08, 2002 APPLICATION NOTE 168 DS1869 Digital Potentiometer Modes of Operation Abstract: The DS1869 is a 64-position digital potentiometer with "up/down" control, which allows adjustment in a manner similar to mechanical potentiometers. The device has three modes of operation which allow control either from a single pushbutton, double pushbutton, or control from a microprocessor or microcontroller, depending on how the chip is hardwired into the……
