Application Scenarios & Design Considerations

PRECISION 4.0 VOLT MICROPOWER

Alternative Part Number

  • LM4040A40IDBZR --: Precision 4.096V shunt voltage reference in SOT-23, functionally equivalent to the ZRA400N801 with tight tolerance and wide availability.
  • ADR4540BRZ --: High-accuracy 4.096V series voltage reference, suitable replacement where improved stability and low drift are required.
  • TL431ACDBZR --: Adjustable shunt reference that can be set to 4.096V, widely used and cost-effective alternative for general reference applications.
  • ADR4540ARZ --: High-accuracy 4.096V series voltage reference, suitable where a stable 4V-class reference is required and a series topology is acceptable.
  • MAX6006AEUR-T --: Low-power 4.096V shunt reference in a small package, offering a compact alternative for 4V reference applications.
