AD8527ARMZ-REEL

Overview

The AD8527ARMZ-REEL is a dual, low-voltage, rail-to-rail operational amplifier from Analog Devices. It operates on a single supply ranging from 1.8 V to 6 V with a gain-bandwidth product of 7 MHz and a slew rate of 8 V/µs. The device features a maximum input offset voltage of 3.5 mV at 25°C and 5 mV across the extended industrial temperature range of –40°C to +125°C. Supply current is typically 900 µA per amplifier at 5 V. It is housed in an 8-lead MSOP package.

Feature Summary

• Rail-to-rail input and output capability allows full signal swing at supply voltages as low as 1.8 V.
• High-speed performance with a 7 MHz gain-bandwidth product and 8 V/µs slew rate suitable for driving ASIC inputs.
• Low power consumption with typical supply current of 900 µA per amplifier at 5 V.
• Extended industrial temperature operation from –40°C to +125°C.

Applications

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

Procurement Notes

Verify that the ordering suffix 'RM' corresponds to the 8-lead MSOP package and '-REEL' indicates tape-and-reel packaging. Confirm the component meets the specified RoHS compliance standards. Ensure the supplier provides documentation verifying the extended industrial temperature rating of –40°C to +125°C. Cross-reference the manufacturer part number with official Analog Devices databases to confirm authenticity.

Selection Notes

Select this component when space-constrained designs require a dual amplifier in an 8-lead MSOP footprint. It is appropriate for battery-powered applications due to its low supply current and ability to operate down to 1.8 V. Choose this part over the single-channel AD8517 if two amplifiers are needed in a compact form factor. Ensure the application does not require higher bandwidth or lower noise than the 7 MHz GBP and 15 nV/√Hz specifications provide.

Part Context

The AD8527 is the dual-channel variant within the AD85x7 family, which also includes the single-channel AD8517. Both share identical electrical characteristics but differ in package options; the AD8527 is available in SOIC and MSOP packages. This family utilizes Analog Devices' XFCB process to achieve high speed and low power in small surface-mount packages.

Replacement Considerations

The AD8527AR is the same device in an 8-lead SOIC package. The AD8517ART-REEL is the single-channel equivalent in a 5-lead SOT-23 package.

FAQ

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

No, the AD8527 exhibits no phase reversal even if 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 a unity gain configuration, the AD8527 can drive up to 400 pF of capacitance before instability occurs.
