AD8529ARMZ-REEL

Overview

The AD8529ARMZ-REEL is a dual-channel, rail-to-rail output bipolar operational amplifier from Analog Devices. It features an 8 MHz unity gain bandwidth and a typical voltage offset of less than 1 mV. The device operates on single supplies ranging from 2.7 V to 12 V or dual supplies up to ±6 V. Key electrical characteristics include a maximum supply current of 1.4 mA per amplifier, a slew rate of 2.9 V/μs, and a maximum input bias current of 400 nA across the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail output swing capability for increased dynamic range
• Unity gain stability with high bandwidth performance
• Low power consumption suitable for battery-powered applications
• Extended industrial temperature rating for reliable operation

Applications

• Portable communications equipment
• Microphone amplifiers and audio preamps
• Sensor interface circuits
• Active filters
• ASIC input drivers

Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. The 'RM' suffix indicates the 8-lead MSOP package, while 'AR' denotes the SOIC variant. Confirm that the '-REEL' designation matches the required tape-and-reel quantity for manufacturing integration. Cross-reference the manufacturer's latest datasheet revision to ensure all electrical specifications remain unchanged before finalizing procurement orders.

Selection Notes

Select this component when dual-channel precision is required alongside rail-to-rail output capabilities in a compact surface-mount footprint. The low supply current makes it appropriate for portable devices where power efficiency is critical. Ensure the application does not require FET-input characteristics, as this bipolar device has higher bias currents compared to CMOS alternatives. Verify that the 8 MHz bandwidth meets the signal processing requirements of the target circuit design.

Part Context

This part belongs to the AD8519/AD8529 family of 8 MHz rail-to-rail operational amplifiers manufactured by Analog Devices. While the AD8519 is a single-channel device available in SC70 and SOT-23 packages, the AD8529 provides two channels in 8-lead SOIC and MSOP packages. Both share identical electrical performance metrics and are designed for low-voltage, battery-operated systems requiring high precision and speed.

Replacement Considerations

The AD8529AR serves as the tube-packaged equivalent of the AD8529ARZ-REEL. For single-channel applications, the AD8519 series offers identical electrical performance in different physical footprints.
