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 (V
CC
). The resistor string uses its
own analog supplies (V
DD
and V
SS
) that require
V
DD
- V
SS
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 V
DD
- V
SS
and V
CC
-
V
SS
are met.
The MAX5437/MAX5439 include an on-chip, high-
voltage, uncommitted amplifier, providing additional
reductions in board space and cost. Other features
include low 35ppm/°C end-to-end and 5ppm/°C ratio-
metric 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 14-
pin TSSOP package. Each device is guaranteed over
the extended temperature range of -40°C to +85°C.
