MAX5436–MAX5439
General Description
The MAX5436–MAX5439 are 128-tap high-voltage (±5V
to ±15V) digital potentiometers in packages that are half
the size of comparable devices in 8-pin SO. They perform
the same function as mechanical potentiometers, but
replace the mechanics with a simple digital interface. The
digital logic is powered by a separate single +2.7V to
+5.25V supply voltage (VCC). The resistor string uses its
own analog supplies (V DD and V SS ) that require
VDD - VSS to be greater than 9V and less than 31.5V. This
allows for greater flexibility in voltage ranges that can be
used with these devices. Examples of analog supply
ranges include not only dual voltages of ±5V to ±15V, but
single-supply voltages, such as +10V, +15V, +30V, -30V,
and more, as long as the ranges of VDD - VSS and VCC VSS are met.
The MAX5437/MAX5439 include an on-chip, highvoltage, uncommitted amplifier, providing additional
reductions in board space and cost. Other features
include low 35ppm/°C end-to-end and 5ppm/°C ratiometric resistor temperature coefficients, a 3-wire SPI™/
QSPI™/MICROWIRE™-compatible serial interface, and
a power-on reset to midscale.
The MAX5436/MAX5438 are available in 10-pin µMAX
packages. The MAX5437/MAX5439 are available in 14pin TSSOP package. Each device is guaranteed over
the extended temperature range of -40°C to +85°C.

Note 1: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDD and L = VSS. The
wiper terminal is unloaded.
Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = VSS.
The wiper terminal is driven with a source current of 80µA for the 50kΩ configuration and 40µA for the 100kΩ configuration.
Note 3: The wiper resistance is measured assuming the source currents given in Note 2.
Note 4: The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between
(VCC - 0.5V) and (GND + 0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics section.
Note 5: Guaranteed by design and characterization.

Detailed Description
Digital Interface Operation
The MAX5436–MAX5439 use a 3-wire SPI/QSPI/
MICROWIRE-compatible serial data interface to control
the wiper position. This write-only interface contains
three inputs: chip select (CS), data in (DIN), and serial
clock (SCLK). When CS is taken low, data from DIN is
synchronously loaded into the serial shift register on the
rising edge of each SCLK pulse (Figure 2). The 8-bit
data word requires 8 clock pulses to input the serial
data. Note that the first bit of the data word, D7, is
unused and should be ignored. Therefore, the second
rising edge of SCLK loads the MSB. After all the data
bits have been shifted in, they are latched into the
potentiometer control register when CS transitions from
low to high, the wiper position is then updated. Note
that if CS is not kept low during the entire data stream,
the data will be corrupted and the device will need to
be reloaded.
Adjustable Gain Amplifier
The MAX5436/MAX5438 are used with the MAX427 to
make a digitally adjustable gain circuit as shown in
Figure 4. The normal feedback resistor is replaced with
the MAX5436/MAX5438 in a variable-resistor configuration so that the gain of the circuit can be digitally controlled. The MAX5437/MAX5439 can use the internal
high-voltage amplifier to make this digitally adjustable
gain circuit.
LCD Biasing Control Applications
The MAX5436–MAX5439 are ideal for LCDs that require
separate voltage for contrast control in addition to the
main supply voltage. Figure 5a shows the MAX5436–
MAX5439 being used for LCD contrast control along with
the MAX629, which provides the LCD supply voltage. A
similar circuit with an additional buffer circuit is shown in
Figure 5b.
Applications Information
Power-Up Sequencing
The MAX5436–MAX5439 have been designed so that
any of the supplies can turn on first without causing any
unwanted crowbar currents to flow. Note that both digital
and analog supplies are required to power up the wiper
and uncommitted amplifier (MAX5437/MAX5439 only).
