Low Noise, Low Power, 100 Taps, Digitally Controlled Potentiometer (XDCP™)
The X9317 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.
Features
The potentiometer is implemented by a resistor array
composed of 99 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.
• 100 wiper tap points
- Wiper position stored in nonvolatile memory and recalled
on power-up
The device can be used as a three-terminal potentiometer for
voltage control or as a two-terminal variable resistor for current
control in a wide variety of applications.
• Low power CMOS
- VCC = 2.7V to 5.5V, and 5V ±10%
- Standby current
