General Description
The MAX5427/MAX5428/MAX5429 linear-taper digital
potentiometers function as mechanical potentiometers,
but replace the mechanics with a simple 2-wire digital
interface. These digital potentiometers are unique in that
they have an optional one-time programmable feature
that either sets the wiper’s power-on reset (POR) posi-
tion to a user-defined value, or the wiper can be set and
the interface disabled to prevent further adjustment.
The MAX5427 has an end-to-end resistance of 100k
,
the MAX5428 a resistance of 50k
, and the MAX5429 a
resistance of 10k
. All these devices have 32 wiper
positions, operate from a single 2.7V to 5.5V supply, and
use less than 1.5A (max) static supply current.
The MAX5427/MAX5428/MAX5429 are available in
8-pin thin QFN and MAX packages. Each device is
guaranteed over the extended temperature range of
-40°C to +85°C.
