General Description
The MAX5527/MAX5528/MAX5529 linear-taper digital
potentiometers perform the same function as mechanical
potentiometers, replacing the mechanics with a simple
2-wire up/down digital interface. These digital poten-
tiometers provide an optional one-time programmable
feature that sets the power-on reset position of the wiper.
Once the wiper position is programmed, the 2-wire inter-
face can be disabled to prevent unwanted adjustment.
The MAX5527/MAX5528/MAX5529 provide an end-to-end
resistance of 100kΩ, 50kΩ, and 10kΩ, respectively. The
devices feature low temperature coefficients of 35ppm/°C
end-to-end and 5ppm/°C ratiometric. All devices offer 64
wiper positions and operate from a single +2.7V to +5.5V
supply. An ultra-low, 0.25µA (typ) standby supply current
saves power in battery-operated applications.
The MAX5527/MAX5528/MAX5529 are available in
3mm x 3mm, 8-pin TDFN and 5mm x 3mm, 8-pin
µMAX®packages. Each device is guaranteed over the
-40°C to +105°C temperature range.

Detailed Description
The MAX5527/MAX5528/MAX5529 100kΩ/50kΩ/10kΩ
end-to-end resistance digitally-controlled potentiome-
ters offer 64 wiper tap positions accessible along the
resistor array between H and L. These devices function
as potentiometers or variable resistors (see Figure 1).
The wiper (W) position is adjusted sequentially through
the tap positions using a simple 2-wire up/down inter-
face. These digital potentiometers provide an optional
one-time programmable feature that sets and locks the
power-on reset position of the wiper (see the
PV One-
Time Programming
section). Once the desired wiper
position is programmed, the 2-wire interface can be
disabled to prevent unwanted adjustment.
Digital Interface Operation
The MAX5527/MAX5528/MAX5529 provide two modes
of operation when the serial interface is active: incre-
ment mode or decrement mode. The serial interface is
only active when CS is low.
The CS and U/Dinputs control the position of the wiper
along the resistor array. Set U/Dhigh to increment the
MAX5527/MAX5528/MAX5529 when CS transitions
from high to low (Figure 2). Set U/Dlow to decrement
the MAX5527/MAX5528/MAX5529 when CS transitions
high to low (Figure 3). Once CS is held low, each low-
to-high transition at U/Dincrements or decrements the
wiper one position. Once the increment or decrement
mode is set, the device remains in that mode until CS
goes high.
Idle U/Dhigh for normal operation. If U/Dis low when
CS transitions low to high, the wiper moves one addi-
tional tap in its present direction. The wiper remains in
the same position when U/Dis high and CS transitions
low to high. After CS returns high, the wiper position
remains the same (Figure 4).
Additional increments do not change the wiper position
when the wiper is at the maximum end of the resistor
array. Additional decrements do not change the wiper
position when the wiper is at the minimum end of the
resistor array.

PV One-Time Programming
The MAX5527/MAX5528/MAX5529 power up and func-
tion after power-up with the wiper position set in one of
three ways:
1) Factory default power-up position, midscale, adjustable
wiper
2) A newly programmed power-up position, adjustable
wiper
3) A new programmed power-up position, locked wiper
The wiper is set to the factory default position at power-
up (midscale, tap 31). Connect PV to GND or leave
floating to continue powering up the wiper position at
midscale. See Table 1 for the default and one-time pro-
gramming options.

Change the wiper’s power-up position using the PV
one-time programming sequence after power-up (see
Figure 5). After setting the wiper to the desired power-
up position, perform the following six-step sequence:
1) Set U/Dand CS high.
2) Connect an external voltage source at PV in the
range of +11V to +11.55V.
3) Pull CS low.
4a) Pulse CS high for six cycles, consisting of CS
starting low and going high for at least tCH, and
then low for at least tCL, to change the wiper
power-up position. The wiper remains adjustable.
4b) Pulse CS high for seven cycles, consisting of CS
starting low and going high for at least tCH and then
low for at least tCL, to change the wiper power-up
position and lock the wiper in that same position.
The seventh CS pulse is labeled the optional lock-
out bit in Figure 5.
5) Connect PV to GND or release the voltage source,
leaving PV floating.
6) Pull CS high.
Pulse CS high for six cycles to change the wiper power-
up position. The wiper position returns to this pro-
grammed position on power-up, but remains adjustable.
Pulse CS high for seven cycles to lock the MAX5527/
MAX5528/MAX5529 to a specific wiper position with no
further adjustments allowed. This effectively converts
the potentiometer to a fixed resistor-divider. The sev-
enth pulse locks the wiper position and disables the
up/down interface. Once locked, connect U/Dand CS
high, low, or leave them floating without increasing the
supply current (see Table 1).
If six clock pulses are used, the interface is enabled
and the device can be put into program mode again.
However, the part uses one-time programmable (OTP)
memory and should be programmed only once. If the
part is programmed more than once, all applied values
are ORed together. Thus, if 010101 is programmed the
first time and 101010 is programmed the second time,
the result will be 111111.
The external PV power supply must source at least 5mA
and have a good transient response. Decouple the PV
power supply with a 22µF capacitor to GND. Ensure that
no more than 250µH of inductance and/or 40Ωof para-
sitic resistance exists between the capacitor and the
device (see Figure 6).

Applications Information
Use the MAX5527/MAX5528/MAX5529 in applications
requiring digitally controlled adjustable resistance,
such as LCD contrast control where voltage biasing
adjusts the display contrast, or for programmable filters
with adjustable gain and/or cutoff frequency.
Positive LCD Bias Control
Figures 7 and 8 show an application where the voltage-
divider or variable resistor is used to make an adjustable,
positive LCD bias voltage. The op-amp provides buffer-
ing and gain to the resistor-divider network made by the
potentiometer (Figure 7), or to a fixed resistor and a
variable resistor (Figure 8).
Programmable Filter
Figure 9 shows the configuration for a 1st-order pro-
grammable 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), only up to frequencies one
decade below the wiper -3dB bandwidth.
Adjustable Voltage Reference
Figure 10 shows the MAX5527/MAX5528/MAX5529

reference application.

Layout and Power-Supply Considerations
Proper layout and power-supply bypassing can affect
device performance. Bypass VDD with a 0.1µF capacitor
as close to the device as possible. When programming
the wiper position, bypass PV with a 22µF capacitor as
close to the device as possible. For a VDD power supply
with a slew rate greater than 1V/µs or in applications
where power-supply overshoot is prevalent, connect a
10Ωresistor in series to VDD and bypass VDD with an
additional 4.7µF capacitor to ground.
