DESCRIPTION
The X9401 integrates 4 digitally controlled potentiome-
ters (XDCP) on a monolithic CMOS integrated
microcircuit.
The digitally controlled potentiometer is implemented
using 64 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 SPI bus
interface. Each potentiometer has associated with it a
volatile Wiper Counter Register (WCR) and 4 nonvola-
tile Data Registers (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 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.
