The X96012 is a highly integrated bias controller which incorporates two digitally controlled Programmable Current Generators, temperature compensation with dedicated look-up tables, and supplementary EEPROM array. All functions of the device are controlled via a 2wire digital serial interface. Two temperature compensated Programmable Current Generators, vary the output current with temperature according to the contents of the associated nonvolatile look-up table. The look-up table may be programmed with arbitrary data by the user, via the 2wire serial port, and either an internal or external temperature sensor may be used to control the output current response. The integrated General Purpose EEPROM is included for product data storage.
