RH1021-7
Precision 7V Reference
DESCRIPTION
The RH1021-7 is a precision 7V reference with ultralow
drift and noise, extremely good long-term stability and
almost total immunity to input voltage variations. The
reference output will source and sink up to 10mA. This
reference can also be used as a shunt regulator
(2-terminal Zener). Unique circuit design makes the
RH1021-7 the first IC reference to offer ultralow drift
without the use of high power on-chip heaters.
The wafer lots are processed to Linear Technology鈥檚 in-
house Class S flow to yield circuits usable in stringent
military applications.
