PRELIMINARY TECHNICAL DATA
Nonvolatile Memory Programmable Resistors
Note that in the zero-scale condition a finite wiper resistance of
50
is present. Care should be taken to limit the current flow
between W and B in this state to no more than 20mA to avoid
degradation or possible destruction of the internal switches.

The typical distribution of full scale R
WB
from channel-to-
channel matches to ±0.2% within the same package. Device to
device matching is process lot dependent with the worst case of
±30% variation. On the other hand, the change in R
WB
with
temperature has a 35ppm/°C temperature coefficient.
