Manufacturer Part Number
x93154ux8i-3t1
Description
Digitally Controlled Potentiometer Xdcp?
Manufacturer
Intersil Corporation
Datasheet
Digitally Controlled Potentiometer
(XDCP™)
The Intersil X93154 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. 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 is connected as a two-terminal variable resistor
and can be used in a wide variety of applications including:
Pinouts
- Bias and Gain Control
- LCD Contrast Adjustment
