The DS1859 dual, temperature-controlled, nonvolatile
(NV) variable resistors with three monitors consists of
two 50kΩ or two 20kΩ, 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.
