LM169/LM369 Precision Voltage Reference
General Description
The LM169/LM369 are precision monolithic temperature-
compensated voltage references. They are based on a bur-
ied zener reference as pioneered in the LM199 references,
but do not require any heater, as they rely on special tem-
perature-compensation techniques (Patent Pending). The
LM169 makes use of thin-film technology enhanced by the
discrete laser trimming of resistors to achieve excellent
Temperature coefficient (Tempco) of V
out
(as low as 1
ppm/
§
C), along with tight initial tolerances (as low as 0.05%
max). The trim scheme is such that individual resistors are
cut open rather than being trimmed (partially cut), to avoid
resistor drift caused by electromigration in the trimmed area.
The LM169 also provides excellent stability vs. changes in
input voltage and output current (both sourcing and sinking).
The devices have a 10.000V output and will operate in ei-
ther series or shunt mode; the output is short-circuit-proof to
ground. A trim pin is available which permits fine-trimming of
V
out
, and also permits filtering to greatly decrease the out-
put noise by adding a small capacitor (0.05 to 0.5
m
F).
