General Description
The MAX5487/MAX5488/MAX5489 dual, linear-taper,
digital potentiometers function as mechanical poten-
tiometers with a simple 3-wire SPI-compatible digital
interface that programs the wipers to any one of 256
tap positions. These digital potentiometers feature a
nonvolatile memory (EEPROM) to return the wipers to
their previously stored positions upon power-up.
The MAX5487 has an end-to-end resistance of 10k
,
while the MAX5488 and MAX5489 have resistances of
50k
and 100k, respectively. These devices have a
low 35ppm/°C end-to-end temperature coefficient, and
operate from a single +2.7V to +5.25V supply.
The MAX5487/MAX5488/MAX5489 are available in
16-pin 3mm x 3mm x 0.8mm TQFN or 14-pin TSSOP
packages. Each device is guaranteed over the extended
-40
°C to +85°C temperature range.
