LM1403 LM1403A
Precision 2 50V Reference
General Description
The LM1403 is a precision monolithic temperature-com-
pensated voltage reference The LM1403 makes use of
thin-film technology enhanced by the discrete laser trim-
ming of resistors to achieve excellent Temperature coeffi-
cient (Tempco) of VOUT (as low as 11 ppm 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 LM1403 also provides
excellent stability vs changes in input voltage and output
current The output is current-limited and is short circuit
proof
