描述 Description

General Description
The LM1403 is a precision, monolithic, temperature-compensated voltage reference. The LM1403 makes use of thin-film technology enhanced by the discrete laser trimming of resistors to achieve excellent Temperature coefficient (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 electromigration 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.
