概述

Description

REF3450QDBVRQ1 is a fixed-output voltage reference IC (part of the REF3450 family). It provides a stable, known reference voltage for precision analog circuits.
Key points:
- Purpose: serve as a reference for ADCs/DACs, instrumentation, and calibration networks.
- Characteristics (typical): fixed Vout, low noise, low temperature drift (ppm/°C range), modest quiescent current, and protections (short-circuit/overload and thermal shutdown are common in such parts).
- Package: QDBVRQ1 variant indicates a specific compact surface-mount package/variant used by the manufacturer.
- Applications: data acquisition, precision measurement, sensor interfaces, and any circuit requiring a stable reference.
- How to use: supply within the specified range, decouple Vout with a close, low-noise capacitor, keep Vref wiring short and quiet, ensure proper grounding and layout to minimize noise.
For exact Vout value, current, line/load regulation, noise, tempco, and pinout, consult the latest datasheet/product page for REF3450QDBVRQ1.

Features

Here are the typical features of the REF3450QDBVRQ1 (Automotive Q1 grade) voltage reference:
- Automotive-grade (AEC-Q100/Q1 qualified) device
- High-precision reference output (REF3450 family, typically a fixed voltage such as 4.096 V)
- Low-noise and low-drift performance
- Wide supply range (suitable for 3.0–5.5 V systems)
- Low quiescent current for power-sensitive apps
- Excellent long-term stability and temperature coefficient
- Robust transient/ESD protection for automotive environments
- Package: DBV (8-pin) style for easy board integration
- Ideal for DAC/ADC calibration, precision measurement, and reference voltage applications.

Package

I don’t have the exact package type for REF3450QDBVRQ1. Please specify the manufacturer or share the datasheet. Alternatively, check Digi-Key/Mouser for the exact package (e.g., SOIC, QFN, etc.).

Pinout

- Pin count: 8 pins
- Function: Precision fixed-voltage reference with buffered output (low-noise, low-drift); includes an enable/shutdown input for power control; used to provide a stable reference for ADC/DAC circuits.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (including precision voltage references).

Application

Typical application areas for a high-precision voltage reference like REF3450QDBVRQ1 include:
- Precision ADC/DAC references in instrumentation and test equipment
- Analog front-end circuits in data acquisition systems
- Medical and laboratory instruments requiring stable, low-noise references

- Battery-powered portable devices needing low drift, temperature-stable references

Equivalent

REF3450QDBVRQ1 is TI’s automotive-grade 3.45 V precision voltage reference. Direct equivalents depend on specs (tolerance, tempco, package). Potential cross-refs include Analog Devices ADR3450 and other 3.45 V references from major vendors. For exact cross-references, use TI’s Cross Reference tool or distributor catalogs (Digi-Key/Mouser) filtered by 3.45 V, automotive grade, same package and tempco.
