The X93254 is a digitally controlled potentiometer from Intersil, consisting of two resistor arrays, two wiper switches, a control section and a non-volatile memory. Two wiper switches individually control the positions of two potentiometers. A potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network. The position of each wiper element is controlled by a set of independent CS, U/D and INC inputs. The position of the wiper can be stored in non-volatile memory and then be recalled upon during a subsequent power-up operation. Each potentiometer is connected as a two-terminal variable resistor and can be used in a wide variety of applications including: Bias and Gain control, LCD Contrast Adjustment.
