CAT5113
100‐tap Digital
Potentiometer (POT)
Description
The CAT5113 is a single digital POT designed as an electronic
replacement for mechanical potentiometers. 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.
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 new system values without affecting 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 digital POT can be used as a three-terminal resistive divider or
as a two-terminal variable resistor.

Device Operation
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 seven−bit 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.
With CS set LOW the CAT5113 is selected and will
respond to the U/D and INC inputs. HIGH to LOW
transitions on INC will 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.
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.
Pin Description
INC: Increment Control Input
The INC input moves the wiper in the up or down direction
determined by the condition of the U/D input.
U/D: Up/Down Control Input
The U/D input controls the direction of the wiper movement.
When in a high state and CS is low, any high−to−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.
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.
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. RL and RH are electrically interchangeable.
CS: Chip Select
The chip select input is used to activate the control input of
the CAT5113 and is active low. When in a high state, activity
on the INC and U/D inputs will not affect or change the
position of the wiper.
