Current Sources and Voltage References

Applying the Intersil/Xicor FGA™ X60008

Additionally, the circuit should be enclosed in a thermally constant environment and

shielded from air currents, which can appear as low-frequency noise voltage, and

stray RFI/EMI, which can also add to the noise figure. Ambient temperature changes,

thermal gradients across active components, or across the circuit board, together with

thermocouple effects, can all become potentially large problems, the more accurate

and stable a reference voltage has to be. The LTZ1000/A is no exception in requiring

great attention to detail. In high-performance converter systems more than 14 bits,

especially where a wide operating ...
