AD8527AR

Overview

The AD8527AR is a dual operational amplifier from the AD8517/AD8527 family, housed in an 8-lead SOIC package. It operates on a single supply ranging from 1.8 V to 6 V with a typical supply current of 900 µA per amplifier at 5 V. Key electrical parameters include a gain bandwidth product of 7 MHz, a slew rate of 8 V/µs, and a maximum input offset voltage of 3.5 mV (5 mV over the extended temperature range). The device features rail-to-rail input and output capabilities, ensuring full signal swing near the supply rails.

Feature Summary

• Rail-to-rail input and output operation allows for maximum dynamic range in low-voltage single-supply applications.
• High-speed performance characterized by a 7 MHz gain bandwidth product and 8 V/µs slew rate.
• Low power consumption suitable for battery-powered devices with minimal supply current draw.

Applications

• Sensor interface circuits
• Active filters
• ASIC input drivers
• Portable communications equipment

Procurement Notes

Verify the specific suffix 'AR' corresponds to the 8-lead SOIC package variant as listed in the ordering guide. Confirm that the component meets the required industrial temperature range specifications (-40°C to +125°C) for your intended deployment environment. Ensure compatibility with the target PCB footprint dimensions provided in the datasheet outline drawings.

Selection Notes

Select this component when dual amplification is required within space-constrained designs utilizing surface-mount technology. The AD8527AR is appropriate for applications demanding rail-to-rail signal handling without phase reversal issues. Consider the 7 MHz bandwidth and low noise characteristics for precision signal conditioning tasks operating from low voltage sources.

Part Context

The AD8527AR belongs to the AD85x7 family of low voltage operational amplifiers manufactured by Analog Devices. This series utilizes a high-speed complementary bipolar process to achieve performance in small packages. The AD8527 specifically provides two independent amplifiers in an 8-lead form factor, complementing the single-channel AD8517 available in SOT-23 packaging.

Replacement Considerations

The AD8527ARM-REEL serves as a functional equivalent within the same family but utilizes an 8-lead MSOP package instead of the SOIC configuration. Designers must verify pinout compatibility and physical footprint differences before substituting between these package types.
