description
The ISL23415 is a volatile, low voltage, low noise, low power, SPI™ bus, 256-tap, single digitally controlled potentiometer (DCP), which integrates the DCP core, wiper switch and control in a monolithic CMOS integrated circuit with a logic digital control potentiometer resistance element and CMOS switch combination implemented. The position of the wipers is controlled by the user via the SPI bus interface. The potentiometer has an associated volatile wiper register (WR) that can be written directly to and from the user. The content of the West Iron controls the position of the wipers. The ISL23415's wiper will always start at mid-size (128-tap position), low voltage, low power, and small package when powered on, making it ideal for battery-powered equipment. In addition, the ISL23415 has a V logic pin that allows the operation of the bus down to 1.2V independently of the CC value from V. This allows the DCP to be used in a variety of applications, including as a three-terminal potentiometer or two-terminal variable resistor control, parameters can be connected directly without voltage level translators, and the ISL23415 is a low logic level.
