Overview
The REF02APG4, produced by Texas Instruments, is a precision 5V voltage reference integrated circuit. It is designed to provide a stable 5V output voltage with excellent temperature stability and low noise. The REF02APG4 operates from a single supply with an input range of 8V to 40V and features a very low current drain of 1.4mA maximum. This device is ideal for applications requiring high precision and stability, such as precision regulators, constant current sources/sinks, digital voltmeters, and analog-to-digital (A/D) and digital-to-analog (D/A) converters.
