AD8519ART-REEL7

Overview

The AD8519ART-REEL7 is a single-channel, rail-to-rail output bipolar operational amplifier from the AD8519/AD8529 series. 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 parameters include a maximum offset voltage of 1.4 mV at extended temperatures, a slew rate of 2.9 V/μs, and a supply current of approximately 600 μA per amplifier. It is housed in a 5-lead SOT-23 package.

Feature Summary

• Rail-to-rail output swing capability for increased dynamic range
• Space-saving 5-lead SOT-23 packaging suitable for portable designs
• Low supply current ideal for battery-powered applications
• Unity gain stable operation with high precision

Applications

• Portable communications equipment
• Microphone amplifiers
• Sensor interface circuits
• Active filters
• Voltage reference buffers

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. Ensure the component meets RoHS compliance requirements if necessary by checking for the 'Z' suffix. Confirm the temperature range matches the application needs, as this part supports the extended industrial range. Cross-reference the datasheet revision to ensure all specifications are current before finalizing procurement.

Selection Notes

Select this component when a small footprint and low power consumption are critical alongside moderate bandwidth. The rail-to-rail output makes it suitable for single-supply systems requiring maximum signal swing. Consider the input bias current and offset voltage specifications for precision applications. Verify that the load capacitance does not exceed stability limits defined in the performance characteristics.

Part Context

This part belongs to the AD8519/AD8529 family of 8 MHz rail-to-rail operational amplifiers manufactured by Analog Devices. The AD8519 variant provides a single channel, while the AD8529 offers dual channels. Both share similar electrical characteristics but differ in pin configurations and package options to suit various design constraints.

Replacement Considerations

Direct substitutes within the same family include the AD8519AKS-REEL7 (SC70 package) and AD8519AR-REEL7 (SOIC package). Other single-channel op amps with similar bandwidth and rail-to-rail outputs may be considered, though pin compatibility and exact electrical matching must be verified.
