FUNCTIONAL DESCRIPTION

¯¯

The CAT5110/5118/5119/5123/5124/5125 consist of a

fixed resistor and a wiper contact with 32-tap points

that are digitally controlled through a 2-wire up/down

serial interface. Three end-to-end resistance values

are available: 10kꢀ, 50kꢀ and 100kꢀ.

The CS and U/D inputs control the position of the

¯¯

wiper along the resistor array. When CS transitions

from high to low, the part will go into increment mode

if U/D input is high, and into decrement mode when

U/D input is low. Once the mode is set, the device will

¯¯

remain in that mode until CS goes high again. A low-

The CAT5110/5125 is designed to operate as a

potentiometer. In this configuration, the low terminal of

the resistor array is connected to ground (pin 2).

to-high transition at the U/D pin will increment or

decrement the wiper position depending on the

current mode (Figures 1 and 2).

¯¯

When the CS input transitions to high (serial interface

The CAT5118/5123 performs as a variable resistor. In

this device, the wiper terminal and high terminal of the

resistor array are connected at pin 5. The

CAT5119/5124 is a similar variable resistor, except

the low terminal is connected to pin 5.

inactive), the value of the counter is stored and the

wiper position is maintained.

Note that when the wiper reaches the maximum (or

minimum) tap position, the wiper will not wrap around

to the minimum (or maximum) position.

Digital Interface Operation

Power-On Reset

The MiniPots have two modes of operation when the

serial interface is active: increment and decrement

All parts in this family feature power-on reset (POR)

circuitry that sets the wiper position to midscale at

power-up. By default, the chip is in the increment mode.
