DESCRIPTION
The X96012 is a highly integrated bias controller which
incorporates two digitally controlled Programmable Cur-
rent Generators, temperature compensation with dedi-
cated look-up tables, and supplementary EEPROM
array. All functions of the device are controlled via a 2-
wire digital serial interface.
Two temperature compensated Programmable Cur-
rent Generators, vary the output current with tempera-
ture 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 2-
wire serial port, and either an internal or external tem-
perature sensor may be used to control the output cur-
rent response.
The integrated General Purpose EEPROM is included
for product data storage.
