描述
ISL23415 is a volatile, low-voltage, low-noise, low-power, SPI™ bus, 256-tap, single digital control potentiometer (DCP) that integrates the core of the DCP, the wiper switch and the logic digital control potentiometer resistor element and CMOS switch controlled in a monolithic CMOS integrated circuit. The position of the wipers is controlled by the user via the SPI bus interface. The potentiometer has an associated volatile wiper registration (WR) that can be written and read directly to the user. The content of Westiron controls the position of the wipers. ISL23415 wipers always start to ISL23415 in medium size (128 tap position), low voltage, low power consumption, small package when powered up, making them ideal for using battery-powered devices. In addition, the ISL23415 has a V logic pin that allows for a drop to 1.2V bus operation from V independent CC values. This allows the DCP to be used in a variety of applications, including as a three-terminal potentiometer or as a double-ended variable resistor control, where parameters can be directly connected without a voltage level converter ISL23415 to low logic levels.
