Detailed Description
The MAX5417/MAX5418/MAX5419 contain a resistor
array with 255 resistive elements. The MAX5417 has a
total end-to-end resistance of 50k
, the MAX5418 has
an end-to-end resistance of 100k
, and the MAX5419
has an end-to-end resistance of 200k
. The
MAX5417/MAX5418/MAX5419 allow access to the high,
low, and wiper terminals for a standard voltage-divider
configuration. H, L, and W can be connected in any
desired configuration as long as their voltages fall
between GND and VDD.
A simple 2-wire I2C-compatible serial interface moves
the wiper among the 256 tap points. A nonvolatile mem-
ory stores the wiper position and recalls the stored wiper
position in the nonvolatile memory upon power-up. The
nonvolatile memory is guaranteed for 50 years for wiper
data retention and up to 200,000 wiper store cycles.
