LM368-5 0 and LM368-10 Precision Voltage References
General Description
The LM368 is a precision monolithic temperature-compen-
sated voltage reference The LM368 makes use of thin-film
technology enhanced by the discrete laser trimming of re-
sistors to achieve excellent Temperature coefficient
(Tempco) of VOUT (as low as 5ppm C) along with tight
initial tolerance (as low as 0 02%) The trim scheme is such
that individual resistors are cut open rather than being
trimmed (partially cut) to avoid resistor drift caused by elec-
tromigration in the trimmed area The LM368 also provides
excellent stability vs changes in input voltage and output
current (both sourcing and sinking) This device is available
in output voltage options of 5 0V and 10 0V and will operate
in both series or shunt mode Also see the LM368-2 5 data
sheet for a 2 5V output The devices are short circuit proof
when sourcing current A trim pin is made available for fine
trimming of VOUT or for obtaining intermediate values with-
out greatly affecting the Tempco of the device
