Digitally-Controlled Potentiometer  
FEATURES  
• 32 Taps  
DESCRIPTION  
The Xicor 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 wiper output with  
• Three-wire Up/Down Serial Interface  
• V = 2.7V & 5V  
CC

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. Direction the wiper moves is  
determined by the state of the Up/Down pin. The wiper  
position at power up is tap #15.  
CC  
• Standby current = 1µA Max.  
• R = 50KΩ  
TOTAL  
• Packages, SOIC-8  
The X9015 can be used in a wide variety of applications  
that require a digitally controlled variable resistor to set  
analog values.
