Characteristics subject to change without notice CAT5110, CAT5118, CAT5119, CAT5123, CAT5124, CAT5125 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: 10kΩ, 50kΩ and 100kΩ. 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 1 and 2). 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). When the CS input transitions to high (serial interface inactive), the value of the counter is stored and the wiper position is maintained. 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. 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 mode. The serial interface is only active when CS is low. All parts in this family feature power-on reset (POR) circuitry that sets the wiper position to midscale at powerup. By default, the chip is in the increment mode. Figure 1. Serial Interface Timing Diagram, Increment Mode CS t CU t IC t IL U/D t IH t CI t SETTLE t SETTLE W Note: "W" is not a digital signal.

E CAT5110, CAT5118, CAT5119, CAT5123, CAT5124, CAT5125 Applications Information Adjustable Gain The MiniPots are intended for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control, where voltage biasing adjusts the display contrast. 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. 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 3. Figure 4 shows a similar circuit for the CAT5119/CAT5124. Figure 3.
