    Docket ↓
    Ultra Precision Reference
    Features Description 1.2µVP-P Noise 2µV/√kHr Long-Term Stability
    n Very Low Hysteresis
    n 0.05ppm/°C Drift
    n Temperature Stabilized
    n 400°C/W Thermal Resistance for LTZ1000A Reduces
    Insulation Requirements
    n Specified for –55°C to 125°C Temperature Range
    n Offered in TO-99 package 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/√kHr. Applications n n n 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.
    The LTZ1000 and LTZ1000A references can provide superior performance to older devices such as the LM199,
    provided that the user implements the heater control and
    properly manages the thermal layout. To simplify thermal
    insulation, the LTZ1000A uses a proprietary die attach
    method to provide significantly higher thermal resistance
    than the LTZ1000. Voltmeters
