DS1856
General Description
The DS1856 dual, temperature-controlled, nonvolatile
(NV) variable resistors with three monitors consists of
two 256-position, linear, variable resistors; three analog
monitor inputs (MON1, MON2, MON3); and a direct-to-
digital temperature sensor. The device provides an
ideal method for setting and temperature-compensating
bias voltages and currents in control applications using
minimal circuitry. The variable resistor settings are
stored in EEPROM memory and can be accessed over
the 2-wire serial bus.
Relative to other members of the family, the DS1856 is
essentially a DS1859 with a DS1852-friendly memory
map. In particular, the DS1856 can be configured so
the 128 bytes of internal Auxiliary EEPROM memory is
mapped into Main Device Table 00h and Table 01h,
maintaining
compatibility
between
both
the
DS1858/DS1859 and the DS1852. The DS1856 also
features password protection equivalent to the DS1852,
further enhancing compatibility between the two.
