com Rev 1; 6/04 Dual Temperature-Controlled Resistors with External Temperature Input and Monitors General Description 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.
