description
The ISL23315 is a volatile, low voltage, low noise, low power consumption, I2C-bus, 256-tap ™, single digitally controlled potentiometer (DCP), which integrates DCP core, wiper switch and control logic in a monolithic CMOS integrated circuit. Implements a combination of resistive elements and CMOS switches for digitally controlled potentiometers. The position of the wipers is controlled by the user via the I2 C-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 ISL23315's wiper will always start at mid-size (128-tap position), low voltage, low power consumption, and small package when powered on, making it ideal for battery-powered devices. In addition, the ISL23315 has a V logic pin that allows the operation of a bus down to 1.2V independent 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 ISL23315 is a low logic level.
