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 1.2mVP-P of noise and long term stability of 2mV/kHr.

Included on the chip is a subsurface Zener reference, a heater resistor for temperature stabilization, and a temperature sensing transistor. External circuitry of LTZ1000A is used to set operating currents and to temperature stabilize the reference. This allows maximum flexibility and best long term stability and noise.

The LTZ1000 and LTZ1000A references can provide superior performance to older references such as the LM199 at the expense of increased circuit complexity and thermal layout considerations. The LTZ1000 is packaged in a standard TO-99 package while the LTZ1000A utilizes a proprietary high thermal resistance die attach which eases thermally insulating the reference.
