AD8527ARZ-REEL

Overview

The AD8527ARZ-REEL is a dual operational amplifier from the AD8517/AD8527 family, manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a gain bandwidth product of 7 MHz and a slew rate of 8 V/µs. The device operates on a single supply voltage ranging from 1.8 V to 6 V, consuming only 900 µA per amplifier at 5 V. It is housed in an 8-lead MSOP package and specified over an extended industrial temperature range of –40°C to +125°C.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing capability even at low supply voltages as low as 1.8 V.
• High-speed performance characterized by a 7 MHz gain bandwidth product and 8 V/µs slew rate suitable for driving ASIC inputs.
• Low power consumption design with typical supply current of 900 µA per amplifier at 5 V, ideal for battery-powered applications.
• Extended industrial temperature specification ensures reliable operation across a wide thermal range from –40°C to +125°C.

Applications

• Portable communications equipment
• Sensor interface circuits
• Active filters
• PCMCIA cards
• ASIC input drivers

Procurement Notes

Verify that the ordering suffix -REEL corresponds to tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the manufacturer is Analog Devices Inc. or an authorized distributor. Ensure the part meets RoHS compliance standards and matches the specified 8-lead MSOP package dimensions. Check for authenticity markers consistent with Rochester Electronics or Analog Devices distribution channels.

Selection Notes

Select this component for designs requiring dual amplifiers with rail-to-rail I/O in space-constrained environments. It is suitable for low-voltage single-supply systems operating between 1.8 V and 6 V. Consider its 7 MHz bandwidth and 8 V/µs slew rate for applications needing moderate speed without high power dissipation. Verify compatibility with the required PCB footprint for the 8-lead MSOP package.

Part Context

The AD8527ARZ-REEL belongs to the AD85x7 family of low voltage operational amplifiers fabricated using Analog Devices' XFCB process. This family includes the single-channel AD8517 and the dual-channel AD8527. The AD8527 variant provides two independent amplifiers in compact surface-mount packages, specifically the 8-lead SOIC and MSOP options, designed for portable and battery-operated electronics.

Replacement Considerations

The AD8527ARM-REEL is a confirmed substitute part number within the same family, offering identical electrical characteristics but potentially differing in specific manufacturing lot details or minor packaging variations. Both parts share the same functional specifications and pinout configuration.

FAQ

Does the AD8527 exhibit phase reversal when the input signal exceeds the supply rails?

No, the AD8527 exhibits no phase reversal as the input signal exceeds the supply by more than 0.6 V.

What is the maximum capacitive load the AD8527 can drive stably in unity gain?

In unity gain configuration, the AD8527 can drive up to 400 pF of capacitance before instability occurs.
