PIN DESCRIPTION

¯¯¯

high state, activity on the INC and U/D inputs will not

affect or change the position of the wiper.

INC: Increment Control Input

¯¯¯

The INC input (on the falling edge) moves the wiper in

the up or down direction determined by the condition

of the U/D input.

DEVICE OPERATION

The CAT5111 operates like a digitally controlled

potentiometer with R_Hand R_Lequivalent to the high

and low terminals and R_WBequivalent to the mecha–

nical potentiometer's wiper. There are 100 available

tap positions including the resistor end points, R_Hand

R_L. There are 99 resistor elements connected in

series between the R_Hand R_Lterminals. The wiper

terminal is connected to one of the 100 taps and

U/D: Up/Down Control Input

The U/D input controls the direction of the wiper

¯¯

movement. When in a high state and CS is low, any

¯¯¯

high-to-low transition on INC will cause the wiper to

move one increment toward the R_Hterminal. When in

a low state and CS is low, any high-to-low transition

¯¯

¯¯¯

on INC will cause the wiper to move one increment

towards the R_Lterminal.

¯¯¯

¯¯

controlled by three inputs, INC, U/D and CS. These

inputs control a seven-bit up/down counter whose

output is decoded to select the wiper position. The

selected wiper position can be stored in nonvolatile

R_H: High End Potentiometer Terminal

R_His the high end terminal of the potentiometer. It is

not required that this terminal be connected to a

potential greater than the R_Lterminal. Voltage applied

to the R_Hterminal cannot exceed the supply voltage,

V_CCor go below ground, GND.

¯¯

memory using the INC and CS inputs.

¯¯

With CS set LOW the CAT5111 is selected and will

¯¯¯

respond to the U/D and INC inputs. HIGH to LOW

¯¯¯

transitions on INC wil increment or decrement the

wiper (depending on the state of the U/D input and

_WB: Wiper Potentiometer Terminal (Buffered)

seven-bit counter). The wiper, when at either fixed

terminal, acts like its mechanical equivalent and does

not move beyond the last position. The value of the

R_WBis the buffered wiper terminal of the poten–

tiometer. Its position on the resistor array is controlled

¯¯¯

¯¯

by the control inputs, INC, U/D and CS.

¯¯

counter is stored in nonvolatile memory whenever CS

¯¯¯

transitions HIGH while the INC input is also HIGH.

R_L: Low End Potentiometer Terminal

When the CAT5111 is powered-down, the last stored

wiper counter position is maintained in the nonvolatile

memory. When power is restored, the contents of the

memory are recalled and the counter is set to the

value stored.

R_Lis the low end terminal of the potentiometer. It is

not required that this terminal be connected to a

potential less than the R_Hterminal. Voltage applied to

the R_Lterminal cannot exceed the supply voltage,

V_CCor go below ground, GND. R_Land R_Hare electri-

cally interchangeable.

¯¯¯

With INC set low, the CAT5111 may be de-selected

and powered down without storing the current wiper

position in nonvolatile memory. This allows the system

to always power up to a preset value stored in non-

volatile memory.

CS: Chip Select

The chip select input is used to activate the control

input of the CAT5111 and is active low. When in a
