The MAX5498 evaluation kit (EV kit) is an assembled
and tested PCB that demonstrates the MAX5498 10-bit
(1024-tap), dual, nonvolatile, SPI™-interface, linear-
taper digital potentiometer. Windows
Windows Vista
user interface to exercise the features of the MAX5498.
The EV kit can also be used to evaluate the MAX5494,
MAX5495, MAX5496, MAX5497, or MAX5499. The
MAX5494/MAX5495 provide two programmable volt-
age-dividers, the MAX5496/MAX5497 provide two vari-
able resistors, and the MAX5498/MAX5499 provide one
programmable voltage-divider and one variable resistor.
The MAX5494/MAX5496/MAX5498 devices have 10kΩ
end-to-end resistance and the MAX5495/MAX5497/
MAX5499 devices have 50kΩ end-to-end resistance.
To evaluate the MAX5494–MAX5497 or MAX5499,
request a free sample (ETE+ suffix) along with the
MAX5498 EV kit.
