Volatile Digitally Controlled Potentiometer (XDCP鈩?
Data Sheet
August 22, 2005
FN6126.0
Terminal Voltage 鹵3V or 鹵5V, 128 Taps
Up/Down Interface
The Intersil ISL23710 is a digitally controlled potentiometer
(XDCP). The device consists of a resistor array, wiper
switches, and a control section. The wiper position is
controlled by a Up/Down interface.
The potentiometer is implemented by a resistor array
composed of 127 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 wiper register is volatile and is reset to midscale on
power up. The wiper position can be locked while powered
up to prevent inadvertent changes.
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including:
