The DS1854 dual temperature-controlled nonvolatile
(NV) variable resistors with two monitors consists of two
50kΩ 256-position linear variable resistors, two analog
monitor inputs (MON1, MON2), 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.
