DS1856 Datasheet | Maxim Integrated

.. Rev 1; 4/05 Dual, Temperature-Controlled Resistors with Internally Calibrated Monitors and Password Protection 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-todigital temperature sensor. The device provides an ideal method for setting and temperature-pensating 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...
