ISL22326WMVEP-TK

The ISL22326WMVEP integrates two digitally controlled potentiometers (XDCP™) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a combination of resistor elements and CMOS switches. The position of the wipers is controlled by the user through the I²C bus interface. Each 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 control the position of the wiper. At power-up, the device recalls the contents of the two DCP's IVR to the corresponding WRs. The DCPs can be used as three-terminal potentiometers or as two-terminal variable resistors in a wide variety of applications including control, parameter adjustments, and signal processing. Device Information The specifications for an enhanced product (EP) device are defined in a vendor item drawing (VID), which is controlled by the Defense Supply Center in Columbus (DSCC).
