FUNCTIONAL DESCRIPTION

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

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

increment or decrement the wiper position depending on the

current mode (Figures 7 and 8).

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:

10 kW, 50 kW and 100 kW.

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).

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.

When the CS input transitions to high (serial interface

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

The devices have two modes of operation when the serial

interface is active: increment and decrement mode. The

serial interface is only active when CS is low.

Power-On Reset

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.

APPLICATIONS INFORMATION

Adjustable Gain

The devices are intended for circuits requiring digitally

controlled adjustable resistance, such as LCD contrast

control, where voltage biasing adjusts the display contrast.

Figures 11 and 12 show how to use either a variable

resistor or a potentiometer to digitally adjust the gain of a

noninverting op amp configuration, by connecting the

devices in series with a resistor to ground. The devices have

a low 5 ppm/C ratiometric tempco that allows for a very

stable adjustable gain configuration over temperature.

Alternative Positive LCD Bias Control

An op amp can be used to provide buffering and gain on

the output of the CAT5110/CAT5125. This can be done by

connecting the wiper output to the positive input of a

noninverting op amp as shown in Figure 9. Figure 10 shows

a similar circuit for the CAT5119/CAT5124.
