Precision 10V Reference
Description
RH1021-10 Precision 10V Reference
DESCRIPTION
The RH1021-10 is a precision 10V 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 RH1021-10 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’s inhouse Class S flow to yield circuits usable in stringent military applications.
