LM268
LM268 is Precision Voltage Reference manufactured by National Semiconductor.
Description
Features
The LM16B/LM36B are precision, monolithic, temperaturepensated voltage references. The LM16B makes use of thin-film technology enhanced by the discrete laser trimming of resistors to achieve excellent Temperature coeffi- cient (Tempco) of VOUT (as low as 5ppml"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 LM16B 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 1O.OV and will operate in both series or shunt mode....
