Application Scenarios & Design Considerations

PRECISION 2.5 VOLT MICROPOWER VOLTAGE REFERENCE

Alternative Part Number

  • LM4040DIZ-2.5 --: Precision 2.5V shunt voltage reference in TO-92 package, functionally equivalent to the ZR4040 series with similar tolerance and current range.
  • TL431ACLP --: Adjustable shunt voltage reference commonly used as a 2.5V reference, widely available and pin-compatible in TO-92, suitable drop-in for many 2.5V reference applications.
  • LM336Z-2.5 --: 2.5V shunt reference diode in TO-92 package with comparable operating current and accuracy, a well-established alternative for 2.5V reference designs.
  • LM4040DIN-8.2 --: Precision 8.2V shunt voltage reference in SOT-23, functionally equivalent to the ZR4040 series with similar tolerance and current range.
  • TL431ACLPR --: Adjustable shunt reference that can be set to 8.2V, widely available and a common substitute for fixed shunt references in many designs.
  • LM4040CIZ-8.2 --: 8.2V shunt reference with tighter tolerance in TO-92, suitable drop-in replacement where through-hole package is acceptable.
