FunCTIOnAl DesCrIPTIOn
The CAT5 0/5 8/5 9/5 23/5 24/5 25 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: 0k Ω, 50k Ω and 00k Ω.
The CAT5 0/5 25 is designed to operate as a potentiometer. In this configuration, the low terminal of the resistor array is connected to ground (pin 2).The CAT5 8/5 23 performs as a variable resistor. In this device, the wiper terminal and high terminal of the resistor array are connected at pin 5. The CAT5 9/5 24 is a similar variable resistor, except the low terminal is connected to pin 5.
DIGITAl InTerFACe OPerATIOn
The MiniPots 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.
Figure 2. serial Interface Timing Diagram, Decrement Mode
Figure 1. serial Interface Timing Diagram, Increment Mode
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 and 2).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. 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.

The MiniPots are intended for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control, where voltage biasing adjusts the display contrast.
AlTernATIVe POsITIVe lCD bIAs COnTrOl An op amp can be used to provide buffering and gain on the output of the CAT5 0/CAT5 25. This can be done by connecting the wiper output to the positive input of a noninverting op amp as shown in Figure 3. Figure 4 shows a similar circuit for the CAT5 9/CAT5 24.
Figure 3. Positive lCD bias Control
Figure 4. Positive lCD bias Control
ADjusTAble GAIn
Figure 5 shows how to use either a variable resistor or a potentiometer to digitally adjust the gain of a noninverting op amp configuration, by connecting the Minipot in series with a resistor to ground. The MiniPots have a low 5ppm/oC ratiometric tempco that allows for a very stable adjustable gain configuration over temperature.
