This sets the baseline accuracy for the ADC or comparator reference before temperature drift and aging are factored in."},{"question":"Will the LT1004IPWR-2-5 drop into a board designed for the LM4040CIM3-3.0/NOPB?","answer":"No — the LM4040CIM3-3.0/NOPB is a 3.0V reference in a SOT-23-3 package, while the LT1004IPWR-2-5 is a 2.5V reference in an 8-TSSOP.
