General Description
The MAX5471/MAX5472/MAX5474/MAX5475 lineartaper digital potentiometers function as mechanical
potentiometers, but replace the mechanics with a simple 3-wire up/down digital interface. These digital
potentiometers feature nonvolatile memory (EEPROM)
to return the wiper to its previously stored position upon
power-up.
The MAX5471/MAX5472 are 2-terminal, variable resistors
in 6-pin SOT23 packages. The MAX5474/MAX5475 are
3-terminal potentiometers in 8-pin SOT23 packages.
The MAX5471/MAX5474 have an end-to-end resistance
of 50kΩ, and the MAX5472/MAX5475 have an endto-end resistance of 100kΩ. All of these devices have
32 wiper positions, a low ratiometric temperature coefficient (5ppm/°C), and all operate from a single +2.7V to
+5.25V supply. Each device is guaranteed over the
extended -40°C to +85°C temperature range.

Note 1: All devices are production tested at TA= +25°C and are guaranteed by design and characterization for -40°C < TA< +85°C.
Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
(MAX5474/MAX5475), H is unconnected and L = GND. At V
DD
= 5.25V, W is driven with a source current of 80µA for the
50kΩ configuration, and 40µA for the 100kΩ configuration. At V
DD
= 2.7V, the wiper terminal is driven with a source current
of 40µA for the 50kΩ configuration, and 20µA for the 100kΩ configuration.
Note 3: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = V
DD
and L = GND
(MAX5474/MAX5475 only). The wiper terminal is unloaded.
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 2 into W with L = GND.
R
W
= (VW- VH) / IW.
Note 5: The device draws higher supply current when digital inputs are driven with voltages between 0.3V x V
DD
and 0.7 x VDD.
Drive the digital inputs as close as possible to V
DD
or GND. (See the Typical Operating Characteristics for the Supply
Current vs. Digital Input Voltage graph.)
Note 6: Wiper at midscale with a 10pF load.
Note 7: Digital timing is guaranteed by design and characterization, and is not production tested.
Note 8: Wiper settling time is the worst-case 0% to 50% rise time measured between consecutive wiper positions. H = V
DD
, L =
GND, and the wiper terminal is unloaded and measured with a 10pF oscilloscope probe (see the Typical Operating
Characteristics for the Tap-to-Tap Switching Transient).

Detailed Description
The MAX5471/MAX5472/MAX5474/MAX5475 contain a
resistor array with 31 resistive elements (Figures 2 and
3). The MAX5471/MAX5474 have a total end-to-end
resistance of 50kΩ, and the MAX5472/MAX5475 have
an end-to-end resistance of 100kΩ. The MAX5471/
MAX5472 wiper is connected to the high terminal, and
the low terminal is internally connected to ground, making the device a variable resistor. The MAX5474/
MAX5475 allow access to the high, low, and wiper terminals for a standard voltage-divider configuration.
The wiper is moved among the 32 tap points through a
simple 3-wire interface. Nonvolatile memory allows the
wiper position to be stored and recalled to the same
point upon power-up.
Digital Interface
Logic inputs CS, U/D, and INC control the wiper position and store it in nonvolatile memory (see the Truth
Table). The chip-select (CS) input enables the serial
interface when low and disables the interface when
high. The position of the wiper is stored when CS transitions from low to high and INC is high (see the Storing
Wiper Position section).
With the serial interface active (CS low), a high-to-low
(falling edge) transition on INC moves the wiper position by one resistive element in the direction determined by the state of U/D. If U/D is high, the wiper
increments and it increases the resistance between W
and L (it decreases the resistance between H and W).
If U/D is low, the wiper decrements and it decreases
the resistance between W and L (it increases the resistance between H and W). The direction of the wiper
(state of U/D) can be changed at any time as long as
the setup and hold times are met.
Since the MAX5471/MAX5472 have the wiper internally
connected to H, an increment command increases the
resistance between H and GND, and a decrement command decreases the resistance between H and GND.
The wiper performs a make-before-break transition,
ensuring that there is never an open circuit during a
transition from one resistor tap to another. When the
wiper is at either end of the resistor array (max/min),
additional transitions in the direction of the endpoint do
not change the counter value (the wiper does not wrap
around).
Storing Wiper Position
The position of the wiper is stored in nonvolatile memory whenever CS transitions low-to-high (rising edge)
while INC is high. Upon power-up, the wiper returns to
this stored position. By keeping INC low while taking
CS high, the serial interface can be disabled and the
potentiometer placed in standby without storing the latest wiper position. The factory-default wiper position
is midscale.
These devices can also be operated like a one-time
programmable (OTP) device. Once the desired wiper
position is trimmed and stored in nonvolatile memory,
disable the serial interface by connecting CS to VDD,
and INC to GND. The disabled interface places the
device in standby and disallows any changes to the
wiper position. In OTP mode, these devices become a
fixed 3-terminal potentiometer or a 1-terminal resistor to
GND with less than 1µA of supply current.

Standby Mode
The MAX5471/MAX5472/MAX5474/MAX5475 are
always in standby mode, except during the transition of
a logic input or while the wiper position is being stored.
When in standby mode, the static supply current is
reduced to less than 1µA and the resistive terminals (H,
W, and L) are unaffected.
Applications Information
The MAX5471/MAX5472/MAX5474/MAX5475 are
intended for circuits requiring digitally controlled
adjustable resistance, such as LCD contrast control
(where voltage biasing adjusts the display contrast), or
programmable filters with adjustable gain and/or cutoff
frequency.
Positive LCD Bias Control
Figures 4 and 5 show an application where the voltagedivider or variable resistor is used to make an
adjustable, positive LCD-bias voltage. The op amp provides buffering and gain to the resistor-divider network
made by the potentiometer (Figure 4) or to a fixed
resistor and a variable resistor (Figure 5).
Programmable Filter
Figure 6 shows the configuration of a 1st-order programmable filter. The gain of the filter is adjusted by
R2, and the cutoff frequency is adjusted by R3. Use the
following equations to calculate the gain (G) and the
3dB cutoff frequency (fC):
