概述
Description
ADR291GRUZ is a fixed-output, precision voltage reference IC from Analog Devices (ADR291 family). It provides a stable, low-noise reference voltage with low drift, suitable for ADC/DAC calibration, instrumentation, and other precision analog applications. The GRUZ suffix denotes a specific packaging/packaging option (e.g., RoHS-compliant, tape-and-reel). Key considerations include output accuracy, temperature coefficient, noise, line/load regulation, and the required operating supply range. Typical use involves placing a bypass capacitor at the output and close-by decoupling, feeding the reference to ADC/DAC inputs, while adhering to the datasheet’s guidelines for voltage, temperature, and packaging. For exact output voltage, performance specs, and packaging details, consult the ADR291 datasheet.
