DESCRIPTION

The X9440 integrates two non volatile digitally con-

trolled potentiometers (XDCP) and two voltage com-

parators on a CMOS monolithic microcircuit.

The X9440 contains two resistor arrays, each com-

posed of 63 resistive elements. Between each ele-

ment and at either end are tap points accessible to the

wiper elements. The position of the wiper element on

the array is controlled by the user through the SPI

serial bus interface.

Each potentiometer has an associated voltage com-

parator. The comparator compares the external input

voltage V

with the wiper voltage V

and sets the out-

put voltage level to a logic high or low.

Each resistor array and comparator has associated

with it a wiper counter register (WCR), analog control

be directly written and read by the user. The contents

of the wiper counter register controls the position of

the wiper on the resistor array. The contents of the

analog control register controls the comparator and its

output. The potentiometer is programmed with a SPI

serial interface.
