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
1.2μV
Included on the chip is a subsurface zener reference, a
heater resistor for temperature stabilization, and a tem-
perature sensing transistor. External circuitry is used to
set operating currents and to temperature stabilize the
reference. This allows maximum fl exibility and best long-
term stability and noise.
The LTZ1000 and LTZ1000A references can provide su-
perior 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 signifi cantly higher thermal resistance
than the LTZ1000.
