概述

Description

ADR291GRUZ is an Analog Devices precision voltage reference (the ADR291 family). It provides a fixed, low-noise reference voltage for instrumentation, ADCs/DACs, and other analog circuits, improving measurement accuracy and stability.
Key points:
- Fixed output reference with tight initial accuracy and low noise
- Low temperature coefficient and good line/load regulation
- Robust operation over the industrial temperature range (and short-circuit protection in many versions)
- GRUZ suffix indicates RoHS-compliant, lead-free, surface-mount packaging (tape-and-reel)
Common uses:
- Precision measurement systems, data acquisition, calibration references, signal conditioning
How to use:
- Supply Vin within the specified range and connect ground
- Take Vout as the precision reference for ADC/DAC circuits
- Place recommended bypass/decoupling capacitors close to the device per the datasheet
For exact voltage value, accuracy, tempco, and package details, consult the ADR291 datasheet and product page.

Features

ADR291GRUZ is a precision voltage reference from Analog Devices. Key features typically include:
- Output: nominal 2.5 V precision reference
- Low drift and high stability over temperature (low tempco)
- Low noise for clean ADC/DAC reference performance
- Tight line and load regulation
- Low quiescent current (suitable for battery-powered systems)
- Wide operating temperature range (-40°C to +125°C)
- Packaging: 8-lead small-outline/MSOP style, GRUZ suffix indicates RoHS-compliant variant
- Suitable for precision instrumentation, data converters, and calibration tasks
Note: for exact figures (tempco ppm/°C, initial accuracy, noise in µV RMS, line/load regulation specs, supply range), please refer to the official ADR291GRUZ datasheet.

Package

ADR291GRUZ uses an 8-pin MSOP package (MSOP-8), RoHS-compliant.

Pinout

- Pin count: 8 pins (MSOP-8/SO-8 style).
- Function: Precision fixed-voltage reference device, providing a stable reference voltage (low-noise, low-drift) for precision analog circuits (e.g., ADC/DAC references).

Manufacturer

ADR291GRUZ is manufactured by Analog Devices, Inc. (ADI). Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP (digital signal processing) integrated circuits and related signal-processing solutions.

Application

ADR291GRUZ is a precision voltage reference (low drift/low noise). Applications:
- Stable reference for ADCs/DACs in data-acquisition, instrumentation, and control systems
- Metrology, calibration, and test equipment
- Portable and medical devices
- Any circuit requiring a reliable, temperature-stable reference

Equivalent

ADR291GRUZ is an Analog Devices precision voltage reference. Exact equivalents depend on the same output voltage, accuracy, and temperature coefficient. Use cross-reference tools (Analog Devices site or Digi-Key/Mouser) by entering ADR291GRUZ to find matching references from TI, Linear/LT, Onsemi, etc., with the same specs and packaging.
