Ideal for automated adjustments on high volume production lines, they are also well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment. new system values without effecting the stored setting. Wiper-control of the CAT5113 is accomplished with three input control pins, CS, U/D, and INC. The INC input increments the wiper in the direction which is determined by the logic state of the U/D input. The CS input is used to select the device and also store the wiper position prior to power down. The CAT5113 contains a 100-tap series resistor array connected between two terminals RH and RL. An up/ down counter and decoder that are controlled by three input pins, determines which tap is connected to the wiper, RW. The wiper setting, stored in nonvolatile memory, is not lost when the device is powered down and is automatically reinstated when power is returned. The wiper can be adjusted to test The digitally programmable potentiometer can be used as a three-terminal resistive divider or as a two-terminal variable resistor. DPPs bring variability and programmability to a wide variety of applications including control, parameter adjustments, and signal processing.

When in a high state, activity on the INC and U/D inputs will not affect or change the position of the wiper. The INC input moves the wiper in the up or down direction determined by the condition of the U/D input. U/D D: Up/Down Control Input DEVICE OPERATION The U/D input controls the direction of the wiper movement. When in a high state and CS is low, any highto-low transition on INC will cause the wiper to move one increment toward the RH terminal. 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 RL terminal. The CAT5113 operates like a digitally controlled potentiometer with RH and RL equivalent to the high and low terminals and RW equivalent to the mechanical potentiometer's wiper. There are 100 available tap positions including the resistor end points, RH and RL. There are 99 resistor elements connected in series between the RH and RL terminals. The wiper terminal is connected to one of the 100 taps and controlled by three inputs, INC, U/D and CS. These inputs control a sevenbit up/down counter whose output is decoded to select the wiper position. The selected wiper position can be stored in nonvolatile memory using the INC and CS inputs. RH: High End Potentiometer Terminal RH is the high end terminal of the potentiometer. It is not required that this terminal be connected to a potential greater than the RL terminal. Voltage applied to the RH terminal cannot exceed the supply voltage, VCC or go below ground, GND. With CS set LOW the CAT5113 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 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 counter is stored in nonvolatile memory whenever CS transitions HIGH while the INC input is also HIGH. When the CAT5113 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. RW: Wiper Potentiometer Terminal RW is the wiper terminal of the potentiometer. Its position on the resistor array is controlled by the control inputs, INC, U/D and CS. Voltage applied to the RW terminal cannot exceed the supply voltage, VCC or go below ground, GND. RL: Low End Potentiometer Terminal RL is the low end terminal of the potentiometer. It is not required that this terminal be connected to a potential less than the RH terminal. Voltage applied to the RL terminal cannot exceed the supply voltage, VCC or go below ground, GND. R L and R H are electrically interchangeable. With INC set low, the CAT5113 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 nonvolatile memory. CS CS: Chip Select The chip select input is used to activate the control input Doc. No. 2009, Rev.
