Tổng quan
Description
Key points:
- Fixed reference with tight initial accuracy and low tempco
- Very low output noise and good line/load regulation
- Typical operating supply range up to about 5.5 V
- Industrial temperature range (roughly -40°C to +125°C)
- DEZ suffix indicates the specific RoHS-compatible package
Notes:
- The ADR4550 family offers multiple output voltage options (e.g., 2.5 V, 4.096 V, etc.); exact values depend on the variant.
- For best performance, follow datasheet guidance on bypass capacitors, layout, and load requirements.
For precise numbers (voltage, noise, tempco, current) refer to the ADR4550DEZ datasheet and the exact variant you’re using.
Equivalent
- LT6655-5 and LT6650-5 (Linear Technology / now Analog Devices)
- TI REF5050/REF5020 (TI’s 5V references)
- MAX6126 (Maxim)
- ADR4550 (same family, bare part)
For exact equivalents, use a distributor cross-reference tool with your exact tolerance, tempco, noise, and package needs.
Features
- Fixed, high-accuracy voltage reference (5.0 V output) suitable for precision ADC/DAC and instrumentation
- Very low noise and fast transient response
- Low drift and excellent long-term stability
- Superior line and load regulation
- Wide operating temperature range
- Low quiescent current for low power consumption
- Robust protection: short-circuit and thermal protection
- Package: 8‑lead DEZ (Pb-free, surface-mount)
- Suitable for precision calibration, voltage reference in instruments and data acquisition systems
Note: For exact electrical specs (accuracy, tempco, noise, regulation, and current) consult the ADR4550DEZ datasheet.
Pinout
- Function: Precision voltage reference (low-noise, low-drift) with a buffered reference output for use as a stable reference voltage for ADCs/DACs.
Manufacturer
- Company type: A global American semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (e.g., precision references, amplifiers, ADCs/DACs).
Application
- Precision ADC/DAC references in data acquisition and instrumentation
- Medical instrumentation and laboratory equipment needing stable VREF
- Industrial automation and process-control instruments
- Automotive and aerospace test, measurement, and calibration gear
- Bench-top and field calibration standards
- Any analog front-end requiring low drift and low noise reference for high-accuracy measurement
