LM268 - Precision Voltage Reference

Features

  • The LM16B/LM36B are precision, monolithic, temperaturecompensated 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.
