AD8529AR

Overview

The AD8529AR is a dual-channel, rail-to-rail output operational amplifier manufactured by Analog Devices Inc. It features an 8 MHz unity gain bandwidth and a typical slew rate of 2.9 V/µs at 5 V supply. The device operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies up to ±6 V. Key electrical characteristics include a maximum input offset voltage of 1.2 mV and a low supply current of 600 µA per channel. It is housed in an 8-lead SOIC package and specified for operation over the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail output swing capability provides greater dynamic range compared to standard video amplifiers.
• Low supply current consumption makes the device suitable for battery-powered applications.
• Small 8-lead SOIC packaging facilitates placement near sensors to reduce external noise pickup.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and RoHS compliance status. Ensure the procurement source provides valid datasheets matching the AD8529 part number. Confirm that the component meets the required operating temperature range specifications before integration into the design.

Selection Notes

Select this component when a dual-channel configuration with rail-to-rail output is required alongside moderate bandwidth. The low supply current and wide operating voltage range make it appropriate for portable devices. Consider the 8-lead SOIC package dimensions for PCB layout constraints and thermal dissipation requirements within the specified industrial temperature limits.

Part Context

The AD8529AR belongs to the AD8519/AD8529 family of precision, low-power operational amplifiers. While the AD8519 is a single-channel variant available in SC70 and SOT-23 packages, the AD8529 provides two channels in an 8-lead SOIC or MSOP package. Both share identical electrical performance characteristics regarding bandwidth, offset voltage, and power consumption.

Replacement Considerations

The AD8529ARMZ is a direct replacement offering the same electrical specifications in an 8-lead MSOP package instead of the SOIC form factor. Verify pinout compatibility and physical footprint differences during substitution planning.
