The DS1858 dual temperature-controlled nonvolatile (NV) variable resistors with three monitors consists of two 50kΩ 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.
