The DS1857 dual temperature-controlled nonvolatile (NV) variable resistors with external temperature input
and monitors consists of two 50kΩ 256-position linear variable resistors, two analog monitor inputs (MON1,MON2), and an external temperature sensor input. 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.
