General Description
Features
The MAX5450–MAX5455 are a family of dual digital
potentiometers that perform the same function as a
mechanical potentiometer or variable resistor. The
MAX5451/MAX5453/MAX5455 have two 3-terminal
potentiometers and the MAX5450/MAX5452/MAX5454
have two 2-terminal variable resistors. The MAX5450–
MAX5455 operate from a +2.7V to +5.5V single-supply
voltage and use an ultra-low supply current of 0.1µA.
These devices consist of two fixed resistors each
with 256 digitally-controlled wiper contacts. The conve-
nient power-on reset (POR) sets the wiper to midscale
position at power-up and the easy-to-use up/down
interface allows glitchless switching between
resistor taps. Six inputs control the 14-pin MAX5451/
MAX5453/MAX5455 potentiometers. Four inputs control
the 10-pin MAX5450/MAX5452/MAX5454 variable resis-
tors.

Coefficient
♦ Power-On Reset Sets Wiper to Midscale
(Position 127)
♦ Glitchless Switching Between the Resistor Taps
♦ 10kΩ, 50kΩ, 100kΩ Resistance Values
The MAX5450–MAX5455 are ideal for applications
requiring digitally-controlled resistors. Three resistance
values are available: 10kΩ, 50kΩ, and 100kΩ. An end-
to-end resistor temperature coefficient of 35ppm/°C
and a ratiometric temperature coefficient of 5ppm/°C
make the MAX5450–MAX5455 excellent choices for
adjustable gain circuit requiring low-temperature drift
The MAX5450–MAX5455 are available in 10-pin µMAX®
and 14-pin TSSOP packages. Each device is guaran-
teed over the extended–industrial temperature range
(-40°C to +85°C).

Note 1: Linearity is defined in terms of the H_ to L_ code-dependent resistance.
Note 2: The DNL and INL are measured with the potentiometer configured as a voltage divider with H_ = V
and L_ = GND. The
DD
wiper terminal is unloaded and measured with an ideal voltmeter.
Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
(MAX5451/MAX5453/MAX5455), H_ is unconnected and L_ = GND. For the 2-terminal potentiometers
(MAX5450/MAX5452/MAX5454), L_ = GND. At V
= +5V, the wiper terminal is driven with a source current of 400µA for the
DD

Note 5: Device draws higher supply current when digital inputs are driven with voltages between (V - 0.5V) and (GND + 0.5V).

(See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics.)
Note 6: Wiper-Settling Time is the worst case 0% to 50% rise-time measured between consecutive wiper positions. H_ = V , L_ =
DD
GND, and the wiper terminal is unloaded and measured with a 10pF oscilloscope probe (see Tap-To-Tap Switching
Transient in the Typical Operating Characteristics).

Detailed Description
Applications Information
The MAX5450–MAX5455 are ideal for adjustable volt-
age or adjustable gain circuits where accurate
adjustable resistances are required.
The MAX5450–MAX5455 contain two independent
resistor arrays each with 255-resistive elements. 256-
tap points are accessible to the wiper along the resistor
arrays between H and L (Figure 2). Power-on reset cir-
cuitry sets the wiper to midscale (position 127) at
power-up.
Adjustable Current to Voltage Converter
Figure 5 shows the MAX5450/MAX5452/MAX5454 with
a MAX4250 low-noise op amp to fine-tune a current to
voltage converter. The physical sizes of both devices
minimize circuit space.
Logic inputs CS, U/D, and INC determine the wiper
position of the MAX5450–MAX5455. With CS low and
U/D high, a high-to-low (falling edge) transition on INC,
increments the internal counter, which increases the
resistance between W and L. When both CS and U/D
are low, a high-to-low INC transition decrements the
internal counter, decreasing the resistance between W
and L (Figure 1). The wiper performs a make-before-
break transition ensuring that there is never an open
circuit during a transition from one resistor tap to anoth-
er. When the wiper is at either end (max/min) of the
resistor array, additional transitions in the direction of
the endpoint will not change the counter value (the
counter will not wrap around).
Adjustable Gain Amplifier
Figures 6a and 6b shows the MAX5450–MAX5455 digi-
tally adjusting the gain of the MAX4493 general-pur-
pose, dual supply op amp. Figure 6a shows the
MAX5450/MAX5452/MAX5454 variable resistor in
series with a resistor to ground to form the adjustable
gain control. Figure 6b shows the MAX5451/MAX5453/
MAX5455 as a 3-terminal potentiometer. In these appli-
cations the low 5ppm/°C ratiometric tempco allows for
a very stable adjustable gain over temperature.
Adjustable Linear Regulator
In Figure 7, the MAX5450/MAX5452/MAX5454 is shown
digitally adjusting the output voltage of the MAX8866
dual linear regulator. In this circuit, the MAX5450/
MAX5452/MAX5454 is connected in series with a resis-
tor to ground to form the adjustable feedback stage.
The 8-bit MAX5450/MAX5452/MAX5454 allows precise
tuning of the output voltage.
The MAX5450/MAX5452/MAX5454 are similar to the
MAX5451/MAX5453/MAX5455 except for internal con-
nections. The MAX5450/MAX5452/MAX5454 internally
connect INC1 to INC2, U/D1 to U/D2, W1 to H1, and
W2 to H2 (Figures 3 and 4). The internal connections
configure the MAX5450/MAX5452/MAX5454 to be vari-
able resistors.
