Non-Volatile/Low Power/2-Wire/64 Taps

The X9241A integrates four digitally controlled

potentiometers (XDCP) on a monolithic CMOS integrated

microcircuit.

The digitally controlled potentiometer is implemented using

63 resistive elements in a series array. Between each

element are tap points connected to the wiper terminal

through switches. The position of the wiper on the array is

controlled by the user through the 2-wire bus interface. Each

potentiometer has associated with it a volatile Wiper Counter

(DR0:DR3) that can be directly written to and read by the

user. The contents of the WCR controls the position of the

wiper on the resistor array through the switches. Power up

recalls the contents of DR0 to the WCR.

The XDCP can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications including control, parameter adjustments, and

signal processing.
