REF02AU Description

Short technical summary and product information.

The Texas Instruments REF02AU is a high-precision 5V voltage reference designed for reliable performance across a wide temperature range. It features a maximum temperature stability of 10ppm/°C from -40°C to +85°C, ensuring consistent output voltage under varying thermal conditions. The device also boasts low noise characteristics (10µV pp max from 0.1Hz to 10Hz), excellent line and load regulation, and is protected against short circuits.

 

Operating from a wide supply voltage range of 8V to 40V, the REF02AU consumes a low supply current of 1.4mA maximum. It is available in an 8-pin SOIC package, suitable for surface-mount applications. The REF02AU is ideal for use in precision regulators, constant current sources/sinks, digital voltmeters, and A/D and D/A converters.

 

This voltage reference is designed for industrial temperature ranges, making it suitable for a variety of test equipment and calibration standards. Its stable 5V output can be externally adjusted over a ±6% range with minimal impact on temperature stability.
