DESCRIPTION
The LTZ
1000 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
P-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 tem-
perature 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.
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 significantly higher thermal resistance
than the LTZ1000.
