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 during 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: - Bias and Gain Control - LCD Contrast Adjustment Pinout X93154 (8 LD MSOP) TOP VIEW INC 1 U/D 2 RH 3 VSS 4 8 VCC 7 CS 6 RL 5 NC* Features Solid-State Potentiometer 3-Wire Serial Interface 32 Wiper Tap Points - Wiper Position Stored in Nonvolatile Memory and Recalled on Power-up 31 Resistive Elements - Temperature Compensated - Maximum Resistance Tolerance of ±30% - Terminal Voltage, 0 to VCC Low Power CMOS - VCC = 3V ±10% - Active Current, 250µA max. - Standby Current, 1µA max.
