CAT5116
Log-Taper, 100-Tap Digitally Programmable Potentiometer (DPP™)
FEATURES
DESCRIPTION
100-position, log-taper potentiometer
Non-volatile EEPROM wiper storage
10nA ultra-low standby current
Single-supply operation: 2.5V – 5.5V
Increment Up/Down serial interface
Resistance value: 32kΩ
The CAT5116 is a log-taper single digitally program-
mable potentiometer (DPP™) designed as a electro-
nic replacement for mechanical potentiometers.
Ideal for automated adjustments on high volume
production lines, DPP ICs are well suited for applica-
tions where equipment requiring periodic adjustment
is either difficult to access or located in a hazardous or
remote environment.
Available in 8-pin MSOP, TSSOP, SOIC and DIP
packages
The CAT5116 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.
APPLICATIONS
Automated product calibration
Remote control adjustments
Offset, gain and zero control
Audio volume control
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 effecting the stored setting.
Sensor adjustment
Motor controls and feedback systems
Programmable analog functions
Wiper-control of the CAT5116 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.
For Ordering Information details, see page 11.
The digitally programmable potentiometer can be used
as a three-terminal resistive divider or as a two-terminal
variable resistor.

movement. When in a high state and CS is low, any
¯¯¯
high-to-low transition on INC will cause the wiper to
The CAT5116 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 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
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,
¯¯¯
¯
¯¯
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
V
CC or go below ground, GND.
¯¯¯
¯¯
the INC and CS inputs.
RW: Wiper Potentiometer Terminal
¯¯
With CS set LOW the CAT5116 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
CAT5116 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 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.
¯¯¯
¯¯¯
With INC set low, the CAT5116 may be deselected
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.
