Overview
The AD8676ARZ is a dual precision operational amplifier from Analog Devices, housed in an 8-lead narrow SOIC package. It features ultralow offset voltage (12 μV typical), low drift (0.6 μV/°C maximum), and very low input bias current (2 nA maximum). The device offers wide bandwidth with a gain-bandwidth product of 10 MHz and rail-to-rail output swing. Operating on supplies from ±5 V to ±18 V, it provides high open-loop gain (120 dB) and excellent noise performance with a voltage noise density of 2.8 nV/√Hz at 1 kHz.
Feature Summary
- Combines ultralow offset voltage and drift with very low input bias currents for high DC precision.
- Features rail-to-rail output swings while maintaining wide bandwidth and low noise characteristics.
- Provides high open-loop gain and common-mode rejection ratio suitable for demanding signal conditioning.
Applications
- Precision instrumentation
- PLL filters
- Strain gage amplifiers
- Medical instrumentation
Procurement Notes
Verify the specific ordering suffix to confirm the package type and reel format. The AD8676ARZ denotes the standard 8-lead narrow SOIC tube packaging. Ensure compatibility with the required temperature range and verify RoHS compliance status indicated by the Z suffix before procurement.
Selection Notes
Select this component when system requirements demand both wide bandwidth and ultra-low noise simultaneously. It serves as a direct replacement for general-purpose amplifiers where rail-to-rail output and superior DC precision are necessary. Consider the 8-lead SOIC footprint for board space constraints.
Part Context
The AD8676ARZ belongs to the AD867x series of ultraprecision, rail-to-rail op amps. It shares architectural similarities with the OP184 regarding output swing but offers significantly lower noise and higher bandwidth. It complements the single-channel AD8675 within the same family.
Replacement Considerations
The AD8676BRZ is available as a grade B version with tighter offset voltage specifications. For single-channel applications, the AD8675 is the corresponding part number within the same series.
FAQ
What is the maximum supply voltage for the AD8676ARZ?
The absolute maximum supply voltage rating is ±18 V.
Does the AD8676ARZ support rail-to-rail output?
Yes, the device features rail-to-rail output swings across its operating temperature range.
