They are designed to provide 7V outputs with temperature drifts of 0.
05ppm/°C, about 1.
2µVP-P of noise and long-term stability of 2µV/√kHr.
Included on the chip is a subsurface zener reference, a heater resistor for temperature stabilization, and a temperature sensing transistor.
External circuitry is used to set operating currents and to temperature stabilize the reference.
This allows maximum flexibility and best longterm stability and noise.
