AD8519ART-REEL

Overview

The AD8519ART-REEL is a single-channel, rail-to-rail output bipolar operational amplifier from Analog Devices. It features an 8 MHz gain bandwidth product and a typical supply current of 600 µA at 5 V. 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 specifications include a maximum input offset voltage of 1.2 mV, a slew rate of 2.9 V/µs, and a common-mode rejection ratio of 100 dB. It is housed in a 5-lead SOT-23 package and is specified for operation over the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail output swing capability providing greater dynamic range than standard video amplifiers.
• Unity gain stability with no phase reversal during large signal transitions.
• Low power consumption suitable for battery-powered applications.
• Small 5-lead SOT-23 packaging allows 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 to confirm the package type and reel quantity. The ART designation indicates a 5-lead SOT-23 package. Ensure the REEL suffix matches the required tape-and-reel configuration for automated assembly processes. Confirm RoHS compliance status if environmental regulations apply to the final product design.

Selection Notes

Select this component when a single-supply, rail-to-rail output amplifier is required in a compact surface-mount package. The 8 MHz bandwidth and 2.9 V/µs slew rate support general-purpose signal conditioning. Consider the low supply current for energy-constrained designs. Verify that the input common-mode voltage range meets the application requirements relative to the chosen supply voltage.

Part Context

This part belongs to the AD8519/AD8529 family of precision, low-power, rail-to-rail output operational amplifiers. The AD8519 represents the single-channel version, while the AD8529 is the dual-channel variant. Both share similar electrical characteristics but differ in channel count and pin configurations. The family is designed to bring precision and bandwidth to space-saving packages like SC70 and SOT-23.

Replacement Considerations

Direct functional substitutes within the same package are not explicitly listed in the provided documentation. Designers should evaluate other single-channel rail-to-rail op-amps with comparable bandwidth and supply current specifications if replacement is necessary.

FAQ

Does the AD8519 exhibit phase reversal?

No, the AD8519 is designed to be unity gain stable and does not exhibit phase reversal.

What is the input common-mode voltage range?

The input common-mode voltage range extends from the negative supply rail (V-) to approximately 0.5 V below the positive supply rail (V+).
