temperature span). Its long-term stability will be around 60 ppm/1000 hours and be
available in a tiny surface-mount package. These specifications are generally suitable
for 10- to 12-bit converter systems.
In summary, the bandgap-based reference has improved with advancements over
time and with the design efforts of several different manufacturers. This has brought
about lower cost, smaller package sizes, better initial accuracy (±%), lower tempco,
lower power, and lower dropout. It is available in a two-terminal shunt format for low-
cost and small-space applications ...
