RH1021-7 - Precision 7V Reference

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's inhouse Class S flow to yield circuits usable in stringent military applications.

Features Ultralow Drift: 5ppm/°C Max Temperature Coefficient Very Low Noise: 4µVP-P (0.1Hz to 10Hz) Long Term Stability: 7ppm/kHr Trimmed Output Voltage Operates in Series or Shunt Mode Configure As Positive Or Negative Reference Output Sinks Or Sources 10mA Available in Metal Can package Total Ionizing Dose (TID) Tolerance, per TM1019.8, MIL-STD-883:- 200kRad (Si), per condition A at 50Rads(Si)/sec Typical Application
