X9313
Digitally Controlled Potentiometer (XDCP™)
April 18, 2007
FN8177.5
Linear, 32 Taps, 3 Wire Interface, Terminal
Voltages ± VCC
The Intersil X9313 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 3-wire interface.
The potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. 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.
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including:
• Control
• Parameter adjustments
• Signal processing

CAUTION: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only; functional
operation of the device (at these or any other conditions above those listed in the operational sections of this specification) is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

NOTES:
1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (VW(n)(actual) - VW(n)(expected)) = ±1 MI maximum.
2. Relative linearity is a measure of the error in step size between taps = RW(n+1) - (RW(n) + MI) = ±0.2 MI.
3. 1 MI = minimum increment = RTOT/31.
