AD8527ARZ-REEL7

Overview

The AD8527ARZ-REEL7 is a dual operational amplifier from the AD8517/AD8527 family, manufactured by Analog Devices Inc. It features a 7 MHz gain bandwidth product and an 8 V/µs slew rate. The device operates on a single supply voltage ranging from 1.8 V to 6 V with a typical supply current of 900 µA per amplifier at 5 V. It offers rail-to-rail input and output capabilities, a maximum input offset voltage of 3.5 mV (5 mV over temperature), and a common-mode rejection ratio of 70 dB. The component is housed in an 8-lead MSOP package and is specified for operation across an extended industrial temperature range of –40°C to +125°C.

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing this specific part number. Confirm the manufacturer is Analog Devices Inc. or an authorized distributor. Ensure the component meets RoHS compliance standards as indicated in the datasheet specifications. Check for authenticity markers consistent with Analog Devices manufacturing practices.

Selection Notes

Select the AD8527ARZ-REEL7 when a dual-channel solution is required for space-constrained designs due to its compact MSOP packaging. Choose this part for applications requiring rail-to-rail signal handling at low voltages. Consider the 7 MHz bandwidth and low offset voltage for precision signal conditioning tasks. Evaluate the 900 µA supply current against system power budget constraints.

Part Context

This component belongs to the AD85x7 family of low voltage operational amplifiers fabricated using Analog Devices' XFCB process. The family includes the single-channel AD8517 and the dual-channel AD8527. The AD8527 variant provides two independent amplifiers in an 8-lead package, offering a cost-effective and space-saving alternative to discrete solutions in portable electronics.

Replacement Considerations

The AD8527ARM-REEL is a direct substitute within the same family, differing only in the specific MSOP package variant designation. Verify pinout compatibility and electrical specifications match before substitution.

FAQ

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

No, the AD8527 does not exhibit phase reversal even if the input signal exceeds the supply voltage by more than 0.6 V.

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

In a unity gain configuration, the AD8527 can stably drive a maximum capacitive load of 400 pF.
