X9C303
Logarithmic Digitally Controlled Potentiometer (XDCP)
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.
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.
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
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.
