DESCRIPTION

The X9221A integrates two digitally controlled potenti-

ometers (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 Register (WCR) and 2 non-

volatile Data Registers (DR0:DR1) 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 con-

tents of DR0 to the WCR.

The XDCP can be used as a three-terminal potentiom-

eter or as a two-terminal variable resistor in a wide

variety of applications including control, parameter

adjustments, and signal processing.
