DESCRIPTION
The LTZ1000 and LTZ1000A are ultra-stable temperature controllable references. 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 per month.
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 long term stability and noise.
