AD8519AR

Overview

The AD8519AR is a single-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 a single supply ranging from 2.7 V to 12 V or dual supplies up to ±6 V. Key electrical characteristics include a 2.9 V/μs slew rate, 600 μA supply current per amplifier, and a maximum input bias current of 300 nA. It is specified over the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Rail-to-rail output swing capability for increased dynamic range
• Space-saving 8-lead SOIC packaging suitable for dense layouts
• Low power consumption ideal for battery-operated systems
• Unity gain stable with high slew rate for driving ASIC inputs

Applications

• Portable communications equipment
• Microphone amplifiers and audio preamps
• Sensor interface circuits
• Active filters
• Battery-powered devices

Procurement Notes

Verify the specific ordering suffix (e.g., REEL vs. REEL7) to confirm tape and reel quantity requirements. Ensure the package option matches the PCB footprint design. Confirm RoHS compliance status if required by manufacturing standards. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability.

Selection Notes

Select this component when a single-channel op amp with rail-to-rail output is required in an 8-lead SOIC package. It is suitable for applications needing 8 MHz bandwidth and low offset voltage. Consider alternative packages like SC70 or SOT-23 if space constraints are tighter. Evaluate power supply voltage ranges to ensure compatibility with the 2.7 V to 12 V operating window.

Part Context

The AD8519AR belongs to the AD8519/AD8529 family of 8 MHz rail-to-rail operational amplifiers. While the AD8519 is a single-channel device, the AD8529 offers dual channels in similar packages. Both share identical electrical specifications but differ in channel count and pin configurations. This family targets portable and battery-powered applications requiring precision and speed.

Replacement Considerations

Direct substitutes within the same family include the AD8519ART (SOT-23 package) and AD8519AKS (SC70 package). For dual-channel needs, the AD8529AR serves as a functional equivalent with two amplifiers. Verify pinout compatibility before substitution, especially between different package types.

FAQ

What is the maximum supply voltage for the AD8519AR?

The absolute maximum supply voltage rating is ±6 V.

Does the AD8519AR support rail-to-rail input?

No, the AD8519AR has rail-to-rail output only; the input common-mode voltage range does not extend to the negative rail.

What is the typical input offset voltage at 25°C?

The typical input offset voltage is 600 μV, with a maximum of 1000 μV at 25°C.
