Product Details

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 our in-house Class S flow to yield circuits usable in stringent military applications.
