X9271UV14IZ Product details

The X9271 integrates a single, digitally controlled
potentiometer (XDCP™) on a monolithic CMOS integrated
circuit.
The digitally controlled potentiometer is implemented by
using 255 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 SPI bus interface. The
potentiometer has associated with it a volatile Wiper Counter
Register (WCR) and four nonvolatile data registers that can
be directly written to and read by the user. The contents of
the WCR control 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 resistor in a wide variety of
applications including control, parameter adjustments, and
signal processing.
