AD8698ARMZ-R2

Overview

The AD8698ARMZ-R2 is a dual precision operational amplifier from Analog Devices, housed in an 8-lead MSOP package. It features rail-to-rail output capability and low noise characteristics. Key electrical parameters include a maximum offset voltage of 100 µV, a maximum offset voltage drift of 2 µV/°C, and a maximum input bias current of 700 pA. The device operates with supply voltages ranging from ±2.5 V to ±15 V and maintains functionality across a temperature range of −40°C to +85°C.

Feature Summary

• Rail-to-rail output maximizes dynamic range for various signal conditioning applications.
• Low offset voltage and drift specifications eliminate the need for manual offset trimming.
• Internal protective circuitry allows input voltages to exceed supply rails without damage.

Applications

• Photodiode amplifiers
• Sensors and controls
• Multipole filters

Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging format for the MSOP variant. Confirm the specific part number against the manufacturer's official ordering guide to ensure correct branding and package option alignment before finalizing procurement orders.

Selection Notes

Select this component when high precision and low noise are critical requirements. The dual configuration offers two independent amplifiers within a single compact package. Ensure the application benefits from the rail-to-rail output swing and the wide common-mode rejection ratio provided by this specific device architecture.

Part Context

This component belongs to the AD8698 series of dual precision operational amplifiers manufactured by Analog Devices. It is designed for applications requiring high accuracy and low power consumption. The series includes variants available in both SOIC and MSOP packages, catering to different space constraints and assembly preferences.

Replacement Considerations

Check the Ordering Guide for equivalent models such as AD8698AR or AD8698ARM-REEL. Verify pinout compatibility and thermal resistance values if substituting between package types like SOIC and MSOP.

FAQ

Does the AD8698 support input voltages exceeding the supply rails?

Yes, the device includes internal protective circuitry that allows input voltages to exceed the supply voltage. However, resistors should be used if inputs exceed the supply by more than 2 V.

Is the AD8698 stable when driving capacitive loads?

The amplifier is stable driving heavy capacitive loads up to 10 nF without compensation. For loads exceeding 50 nF, an external snubber network is recommended to maintain stability.
