Dual, 256-Tap, Low-Drift, Digital Potentiometers
in 14-Pin TSSOP
General Description
Features
The MAX5413/MAX5414/MAX5415 is a family of dual
linear taper digital potentiometers. Each device has two
3-terminal potentiometers. The MAX5413/MAX5414/
MAX5415 operate from +2.7V to +5.5V single-supply
voltages and use an ultra-low 0.1µA supply current.
These devices also provide glitchless switching
between resistor taps, as well as a convenient power-
on reset (POR) that sets the wiper to the midscale posi-
tion at power-up. Each potentiometer consists of a fixed
resistor with a wiper contact that is digitally controlled
through a 3-wire serial interface and has 256 tap points.
It performs the same function as a discrete potentiome-
ter or variable resistor.
o 14-Pin TSSOP Small-Footprint Package
o 256 Tap Positions
o Ultra-Low 0.1µA Supply Current
o +2.7V to +5.5V Single-Supply Operation
o Two Independent Potentiometers in a Package
o Low End-to-End Temperature Coefficient
35ppm/°C
o Low Ratiometric Temperature Coefficient
5ppm/°C
o Power-On Reset: Wiper Goes to Midscale
These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are avail-
able: 10k (MAX5413), 50k (MAX5414), and 100k
(MAX5415). A nominal resistor temperature coefficient
of 35ppm/°C end-to-end and 5ppm/°C ratiometric make
the MAX5413/MAX5414/MAX5415 ideal for applications
requiring low temperature-coefficient variable resistors,
such as adjustable-gain circuit configurations.
(Position 128)
o Glitchless Switching Between Resistor Taps
o 3-Wire SPI™-Interface Compatible
o 10k /50k /100k Resistor Values
The MAX5413/MAX5414/MAX5415 are available in a 14-
pin TSSOP package. Each device is guaranteed over the
extended industrial temperature range (-40°C to +85°C).

Each potentiometer consists of 255 fixed resistors in
The MAX5413/MAX5414/MAX5415 use a 3-wire serial
data interface to control the wiper tap position. This
write-only interface contains three inputs: Chip Select
(CS), Data In (DIN), and Data Clock (SCLK). When CS
is taken low, data from the DIN pin is synchronously
loaded into the serial shift register on each rising edge
of each SCLK pulse (Figure 2). After all the data bits

ground. Circuit space is minimized due to both devices’
packaging.
Adjustable Gain Amplifier
Figure 6 shows how to use the MAX5413/MAX5414/
MAX5415 to digitally adjust the gain of a noninverting op
amp configuration. In Figure 6a, connect the MAX5413/
MAX5414/MAX5415 as a variable resistor in series with a
resistor to ground to form the adjustable gain control of a
noninverting amplifier.
The MAX5413/MAX5414/MAX5415 feature POR circuit-
ry that sets the wiper to the midscale position at power-
up.
Applications Information
The MAX5413/MAX5414/MAX5415 are intended for a
variety of circuits where accurate, fine-tuning adjustable
resistance is required, such as in adjustable voltage or
adjustable gain circuit configurations. It is primarily used
in either a potentiometer divider or a variable-resistor
configuration.
Similarly, Figure 6b shows how to use the MAX5413/
MAX5414/MAX5415 as a 3-terminal potentiometer. In
this application, the MAX5413/MAX5414/MAX5415 low
5ppm/°C ratiometric tempco allows for a very stable
adjustable gain configuration over temperature.

to the ADJ pin of the MAX6160. The MAX5413/
MAX5414/MAX5415 allow precise setting of the voltage
reference output. A low 5ppm/°C ratiometric tempco
allows a very stable adjustable voltage overtemperature.
