AD8648ARZ-REEL

Overview

The AD8648ARZ-REEL is a quad, rail-to-rail input and output operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features a gain bandwidth product of 24 MHz and a slew rate of 11 V/μs. Input offset voltage is typically 0.6 mV with a maximum of 2.5 mV. Supply current per amplifier is 2 mA maximum. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capability for wide dynamic range operation in single-supply systems.
• Low noise performance with 8 nV/√Hz voltage noise density.
• High output drive capability supporting short-circuit currents up to 120 mA.
• Very low input bias current of 1 pA typical value.

Applications

• Battery-powered instruments
• Multipole filters
• ADC front ends
• Sensors
• Barcode scanners

Procurement Notes

Verify the specific package option R-14 (14-Lead SOIC_N) matches the design requirements. Confirm RoHS compliance status as indicated by the Z suffix. Ensure the reel packaging format aligns with automated assembly equipment specifications. Cross-reference the manufacturer part number against authorized distributor lists to validate authenticity.

Selection Notes

Select this component when high bandwidth and precision are required in a quad configuration. The rail-to-rail architecture suits low-voltage single-supply designs. Consider the 24 MHz bandwidth for signal processing applications requiring fast response times. Evaluate thermal resistance characteristics for PCB layout planning under maximum load conditions.

Part Context

This part belongs to the AD8646/AD8647/AD8648 family of precision amplifiers. The AD8648 specifically provides four independent channels in a single package. It shares core electrical characteristics with the dual-channel AD8646 but offers higher channel density. The series is designed for general-purpose analog signal conditioning tasks.

Replacement Considerations

The AD8648ARZ serves as the tube version of this reel-packaged component. Verify pinout compatibility if substituting with other quad amplifiers from the same manufacturer family.
