Data Sheet
September 15, 2005
FN8157.1
Single Digitally Controlled (XDCP™)
Potentiometer
The Intersil X9015 is a 32 tap potentiometer that is volatile.
The device consists of a string of 31 resistors that can be
programmed to connect the R

/V
W
wiper output with any of
the nodes between the connecting resistors. The connection
point of the wiper is determined by information
communicated to the device on the 3-wire port. The 3-wire
port changes the tap position by a falling edge on the
increment pin. The direction the wiper moves is determined by
the state of the up/down pin. The wiper position at power up is
Tap #15.
The X9015 can be used in a wide variety of applications that
require a digitally controlled variable resistor to set analog
values.
