Product Summary

The LM385BDR-1 is a micropower voltage reference. The LM385BDR-1 operates over a 10μA to 20mA current range and feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight voltage tolerance. The band-gap reference for these devices has low noise and long-term stability. The applications of the LM385BDR-1 include Portable Meter References, Portable Test Instruments, Battery-Operated Systems, Current-Loop Instrumentation, and Panel Meters.
