description
ISL23328 is a volatile, low voltage, low noise, low power consumption, 128 tower, dual digitally controlled potentiometer (DCP) one I 2 C bus ™ interface. It integrates two DCP cores, wiper switches and control logic in a monolithic CMOS integrated circuit. Each digital control potentiometer is implemented by a combination of resistive elements and CMOS switches. The position of the wipers is controlled by the user via the I2C bus interface. Each potentiometer has an associated volatile wiper registration (WRI, I = 0,1) that can write and read directly to the user. WRI content controls the position of the wipers. When powered on, each DCP wiper will always start in a medium-sized (64-tap position), low-voltage, low-power, small-package ISL23328, making it ideal for using battery-powered devices. In addition, the ISL23328 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 being connected via a voltage level converter and ISL23328 to low logic levels.
