Single Digitally-Controlled (XDCP™)
Potentiometer
The X9118 is a single digitally controlled potentiometer
(XDCP) on a monolithic CMOS integrated circuit.
The digital controlled potentiometer is implemented using
1023 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. The
potentiometer has associated with it a volatile Wiper Counter
Register (WCR) and a four non-volatile Data Registers 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 though the switches. Power-up recalls the contents of
the default data register (DR0) to the WCR.
The XDCP can be used as a three-terminal potentiometer or
as a two terminal variable resistors in a wide variety of
applications including control, parameter adjustments, and
signal processing.
Features
• 1024 resistor taps – 10-bit resolution
• 2-wire serial interface for write, read and transfer
operations of the potentiometer
• Wiper resistance, 40Ω typical @ 5V
• Four non-volatile data registers for each potentiometer
• Non-volatile storage of multiple wiper positions
• Power on recall: Loads saved wiper position on power-up
• Standby current < 15µA Max
• System VCC: 2.7V to 5.5V operation
• Analog V+/V-: -5V to +5V
• 100kΩ end-to-end resistance
• Endurance: 100,000 data changes per bit per register
• 100 years data retention
• 14 Ld TSSOP
• Low power CMOS
• Pb-free (RoHS compliant)

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-
020.
2. For Moisture Sensitivity Level (MSL), please see product information page for X9118. For more information on MSL, please see tech brief TB363.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
