AD8698ARMZ-REEL

Overview

The AD8698ARMZ-REEL is a dual precision operational amplifier from Analog Devices, packaged in an 8-lead MSOP (RM-8) format and supplied in tape and reel. It features rail-to-rail output capability with a maximum offset voltage of 100 µV and drift below 2 µV/°C. The device operates within a supply voltage range of ±2.5 V to ±15 V, drawing approximately 3.2 mA per amplifier at 25°C. Key electrical specifications include a gain bandwidth product of 1 MHz, a slew rate of 0.4 V/µs, and low input bias current of 700 pA max.

Feature Summary

• Rail-to-rail output maximizes dynamic range across the full supply voltage span.
• Low offset voltage and drift characteristics eliminate the need for manual trimming.
• Internal protective circuitry allows input voltages to exceed supply rails without phase reversal.
• Capable of driving heavy capacitive loads safely without external compensation.

Applications

• Photodiode amplification
• Sensors and controls
• Multipole filters
• Integrator circuits

Procurement Notes

Verify that the ordering suffix matches the required package type, as the MSOP version is available exclusively in tape and reel packaging. Confirm the temperature grade corresponds to the industrial range of −40°C to +85°C. Ensure compatibility with surface-mount assembly processes suitable for the RM-8 footprint. Cross-reference the specific part number against the manufacturer's official ordering guide to validate availability and revision status.

Selection Notes

Select this component when high DC accuracy is required alongside rail-to-rail output swing in a compact surface-mount package. The low input bias current makes it suitable for interfacing with high-impedance sensors. Consider the 1 MHz bandwidth and 0.4 V/µs slew rate for applications requiring moderate speed. Verify that the thermal resistance of the MSOP package meets the system's heat dissipation requirements under continuous operation.

Part Context

This device belongs to the AD8698 family of dual precision amplifiers. The ARMZ designation indicates the MSOP package variant, while the REEL suffix specifies the tape and reel shipping method. It shares core performance characteristics with the SOIC versions but offers a smaller physical footprint. The family is designed for general-purpose precision applications where space and accuracy are critical constraints.

Replacement Considerations

Direct pin-compatible substitutes within the same package include the AD8698AR-REEL and AD8698ARM-R2 variants. These alternatives share identical electrical specifications and functionality. Verify that any replacement maintains the MSOP package form factor if board space is limited. Check for updated revisions or minor parameter variations in newer manufacturing lots.
