AD8676BRZ-REEL

Overview

The AD8676BRZ-REEL is a dual precision operational amplifier from Analog Devices, featuring rail-to-rail output swing and ultralow noise characteristics. It operates within a supply voltage range of ±5 V to ±18 V. Key electrical specifications include a typical input offset voltage of 12 μV, an input bias current of 2 nA maximum, and a gain-bandwidth product of 10 MHz. The device delivers a slew rate of 2.5 V/μs and maintains a low voltage noise density of 2.8 nV/√Hz at 1 kHz. It is housed in an 8-lead SOIC package and supports the extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Combines ultralow offset voltage and drift with very low input bias currents for high dc precision.
• Features rail-to-rail output swing capability to maximize dynamic range in single-supply applications.
• Provides wide bandwidth and low voltage noise suitable for demanding signal processing tasks.

Applications

• Precision instrumentation
• PLL filters
• Strain gage amplifiers
• Medical instrumentation

Procurement Notes

Verify that the ordering suffix REEL corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific grade (B Grade) matches the design requirements for offset voltage limits. Ensure the component is sourced from authorized distributors to guarantee authenticity and adherence to the manufacturer's quality standards.

Selection Notes

Select this component when system designs require both wide bandwidth and exceptional dc accuracy. It is appropriate for applications where minimizing error sources such as offset voltage and thermal drift is critical. Consider its power consumption and package size constraints relative to space-critical equipment requirements.

Part Context

This part belongs to the AD867x series of ultraprecision, rail-to-rail output op amps offered by Analog Devices. It shares architectural similarities with the OP184 regarding output swing but offers superior noise performance. It complements the single-channel AD8675 and quad-channel AD8674 variants within the same family.
