Product details

Fixed 4.5 V output with ±0.1% initial accuracy

The Texas Instruments REF5045AIDR is a precision series voltage reference delivering a fixed 4.5 V output with an initial tolerance of ±0.1%. It operates from an input supply between 4.7 V and 18 V, drawing 1.2 mA quiescent current while sourcing up to 10 mA to the load.

Frequently asked questions

What is the noise performance of REF5045AIDR?

Output noise is 3 µVp-p over the 0.1 Hz to 10 Hz bandwidth, which sets the noise floor for precision analog reference applications.
