The REFS, a robust band-gap and PTAT current reference, is designed to bolster RF, analog, and mixed-signal integrated circuits with significant stability even across varied operational conditions. This component outputs currents and voltages that remain consistent against temperature fluctuations, making it indispensable in high-precision electronic environments. It features multiple outputs referenced to both internal and external resistors, all of which are programmable within a flexibility range of ±30% to support custom calibration needs.
