X9C303  
®
Logarithmic Digitally Controlled Potentiometer (XDCP™)  
Data Sheet  
January 30, 2009  
FN8223.2  
Terminal Voltage ±5V, 100 Taps, Log Taper  
Description  
The Intersil X9C303 is a digitally controlled potentiometer  
(XDCP). The device consists of a resistor array, wiper  
switches, a control section, and nonvolatile memory. The  
wiper position is controlled by a three-wire interface.  
Features  
• Solid-state potentiometer  
• Three-wire serial interface  
• 100 wiper tap points  
- Wiper position stored in nonvolatile memory and  
recalled on power-up  
• 99 resistive elements, log taper  
- Temperature compensated  
- End-to-end resistance, 32kΩ ±15%  
- Terminal voltages, ±5V  
The resistor array is composed of 99 resistive elements.  
Between each element and at either end are tap points  
accessible to the wiper terminal. The position of the wiper  
element is controlled by the CS, U/D, and INC inputs. The  
position of the wiper can be stored in nonvolatile memory  
and then be recalled upon a subsequent power-up  
operation.  
• Low power CMOS  
- VCC = 5V  
- Active current, 3mA max.  
- Standby current, 750µA max.  
The device can be used as a three-terminal potentiometer or  
as a two-terminal variable resistor in a wide variety of  
applications ranging from control, to signal processing, to  
• High reliability  
- Endurance, 100,000 data changes per bit  
- Register data retention, 100 years  
parameter adjustment. Digitally-controlled potentiometers  
provide three powerful application advantages; (1) the  
variability and reliability of a solid-state potentiometer, (2) the  
flexibility of computer-based digital controls, and (3) the use  
of nonvolatile memory for potentiometer settings retention.  
• Packages  
- 8 Ld TSSOP  
- 8 Ld SOIC  
- 8 Ld PDIP  
• Pb-free available (RoHS compliant)
