Analog Devices DS1856 Dual Temperature-Controlled Resistors with three monitors consists of two 256-position, linear, variable resistors; three analog monitor inputs; and a direct-to-digital temperature sensor. The module 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. DS1856 Temperature-Controlled Resistors can be configured so the 128 bytes of internal Auxiliary EEPROM memory is mapped into Main Device Table 00h and Table 01h, maintaining compatibility between both the DS1858 / DS1859 and the DS1852.
