Alternative Part Number

  • ISL21090 --: Renesas (which acquired Intersil/Xicor) offers precision voltage reference families that can replace X5329-type references with similar accuracy and package options.
  • ADR4525 --: High-precision low-noise voltage reference from Analog Devices, suitable as a functional substitute where tight initial accuracy and low drift are required.
  • LM4040 --: Widely available precision shunt voltage reference with multiple voltage grades, a common drop-in style alternative for Xicor reference parts.
