有关 ISL22419 的资源
描述
Support is limited to customers who have already adopted these products.
The ISL22419 integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wiper is controlled by the user through the SPI serial interface. 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. The contents of the WR controls the position of the wiper. At power-up the device recalls the content of the DCP's IVR to the WR. The DCP can be used as a voltage divider in a wide variety of applications including control, parameter adjustments, AC measurement and signal processing.
