RH1021-5
Precision 5V Reference
DESCRIPTION
The RH1021-5 is a precision 5V 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. Unique
circuit design makes the RH1021-5 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.
