The REF80 is a highly integrated
ultra-low drift buried zener precision voltage reference. The REF80 combines a
precision 7.6V reference with an internal heater to achieve extremely low
temperature drift of 0.05ppm/°C. The integrated heater maintains the internal
temperature of the die at a constant set point. This helps the reference voltage
stay constant irrespective of ambient temperature variations. The device internal
temperature is pre-programmed to eliminate design complexities. This allows for
fast design cycles, easy bring up and no dependence on high-cost external precision
components.
The REF80 family is available in a
20-pin LCCC package. The LCCC package is a hermetically sealed ceramic package that
enables ultra-low long-term stability specification of 0ppm (after setteling),
critical for applications that demand a long time period without calibration. The
package also offers excellent immunity against humidity variation.
