AD8675ARMZ-REEL

Overview

The AD8675ARMZ-REEL is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output swing and operates within a supply voltage range of ±5 V to ±18 V (total 10 V to 36 V). Key electrical specifications include a maximum input offset voltage of 75 µV, a typical gain bandwidth product of 10 MHz, and a maximum input bias current of 2 nA. The device exhibits a voltage noise density of 2.8 nV/√Hz at 1 kHz and a slew rate of 2.5 V/µs. It is housed in an 8-lead Mini Small Outline Package (MSOP) and supports the extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Features proprietary nulling capability allowing external compensation for up to 3.5 mV of total system offset error without adversely affecting drift or rejection ratios.
• Combines ultralow offset voltage and drift with very low input bias currents across the full operating temperature range.
• Provides wide bandwidth and rail-to-rail output swings while maintaining low power consumption.

Applications

• Precision instrumentation
• PLL filters
• Laser diode control loops
• Strain gage amplifiers
• Medical instrumentation

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the AD8675 series includes both SOIC and MSOP variants. Confirm RoHS compliance status indicated by the 'Z' suffix. Ensure the reel packaging format aligns with automated assembly requirements. Cross-reference the manufacturer's ordering guide to validate availability and revision history before finalizing procurement orders.

Selection Notes

Select this component when high DC precision and low noise are critical alongside wide bandwidth. The AD8675 is suitable for applications requiring rail-to-rail output operation with minimal signal distortion. Consider the external nulling pins if system-level offset errors exceed internal specifications. Compare against other family members like the AD8676 for dual-channel requirements or the AD8674 for quad-channel needs.

Part Context

The AD8675 belongs to a series of low-noise operational amplifiers offered by Analog Devices. It shares architectural similarities with industry-standard parts like the OP184 and OP07 but offers improved bandwidth and lower noise characteristics. The ARMZ variant specifically denotes the 8-lead Mini Small Outline Package (MSOP), which allows for higher channel density and smaller board footprints compared to standard SOIC packages.

Replacement Considerations

For dual-channel applications, the AD8676 serves as the direct counterpart. For quad-channel configurations, the AD8674 provides equivalent performance metrics. Verify pin compatibility and thermal resistance differences when substituting between package types such as SOIC and MSOP.
