AD8519ARZ

Overview

The AD8519ARZ is a single-channel, rail-to-rail output operational amplifier from Analog Devices. It features an 8 MHz unity gain bandwidth and a 2.9 V/μs slew rate 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. It offers low offset voltage (max 1.2 mV) and low supply current (typical 600 μA). The component is housed in an 8-lead SOIC package and is specified for operation across 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.
• Compact 8-lead SOIC packaging facilitates placement near sensors to reduce external noise pickup.
• Low power consumption makes the device suitable for battery-powered applications.

Applications

• Microphone amplifiers
• Sensor interface circuits
• Active filters
• ASIC input drivers

Procurement Notes

Verify that the ordering suffix matches the required package type, as the AD8519 series includes various options such as SC70 and SOT-23. Confirm RoHS compliance status if environmental regulations apply to the specific manufacturing lot. Ensure the selected variant meets the required operating temperature range specifications for the intended deployment environment.

Selection Notes

Select this component when a single-channel amplifier with rail-to-rail output is required alongside moderate bandwidth. Consider the 8-lead SOIC package for PCB layout constraints where space is limited but through-hole or larger surface-mount footprints are not feasible. Evaluate the trade-off between the 600 μA supply current and the 8 MHz bandwidth against other family members like the AD8529 if dual channels are needed.

Part Context

The AD8519ARZ belongs to the AD8519/AD8529 family of precision, low-power, rail-to-rail output amplifiers. This series is designed to bring precision and bandwidth to small packages. While the AD8519 is a single-channel device, the AD8529 provides dual channels in similar packages. Both share the same core electrical characteristics regarding speed and power efficiency.

Replacement Considerations

The AD8529ARZ serves as a direct functional replacement if dual-channel capability is required within the same package footprint and performance envelope. Other single-channel variants within the AD8519 family may be considered if different packaging options like SC70 or SOT-23 are preferred for space-constrained designs.

FAQ

Does the AD8519ARZ exhibit phase reversal?

No, the datasheet specifies that the AD8519 does not exhibit phase reversal under normal operating conditions.

What is the maximum short-circuit current?

The AD8519ARZ can withstand an instantaneous short circuit to ground with a current rating of ±70 mA.
