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.
