The ISL22416 integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit.该ISL22416集成了数字控制的单电位器（DCP）的集成在一个CMOS集成电路和非挥发性记忆体。

The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches.该数字控制电位器是实施了电阻元件和CMOS开关组合。 The position of the wiper is controlled by the user through the SPI serial interface.该控制抽头位置是通过SPI串行接口的用户。 The potentiometer has an associated volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR) that can be directly written to and read by the user.该电位计具有关联的挥发性抽头寄存器（WR）和非挥发性初值寄存器（IVR​​）的，可以直接写入和由用户读取。 The contents of the WR controls the position of the wiper.WR的内容控制滑动端的位置。 At power-up the device recalls the contents of the DCP's IVR to the WR.在上电时将器件回顾了磷酸氢钙的IVR到西铁的内容。

The DCP can be used as three-terminal potentiometer or as two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.应课税品许可证可作为三端电位计或双端中的应用等多种控制，参数调整，信号处理可变电阻。
