- Integrated heater with temperature stable indicator
- 1/f noise (0.1Hz to 10Hz) : 0.16ppmpk-pk
- Input Voltage range: 10V to 16.5V
- Heater supply range: 10V to 42V
- Hermetically sealed ceramic package (20 pin LCCC)
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 1ppm, critical for applications that demand a long time period without calibration. The package also offers excellent immunity against humidity variation.
