AD8517ART-REEL7

Overview

The AD8517ART-REEL7 is a single-channel, rail-to-rail input and output operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.8 V to 6 V with a typical supply current of 900 µA at 5 V. The device features a gain bandwidth product of 7 MHz and a slew rate of 8 V/µs. Key electrical specifications include a maximum offset voltage of 3.5 mV, an input bias current of 450 nA, and a common-mode rejection ratio of 60 dB. It is housed in a 5-lead SOT-23 package and supports an extended industrial operating temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capability allowing full signal swing across the entire supply voltage range.

• High-speed performance characterized by a 7 MHz gain bandwidth product and 8 V/µs slew rate.
• Compact 5-lead SOT-23 surface-mount packaging designed to minimize board space and external noise pickup.

Applications

• Portable communications equipment
• Sensor interface circuits
• Active filters
• ASIC input drivers
• Battery-powered devices

Procurement Notes

Verify the specific ordering suffix ART-REEL7 to confirm the 5-lead SOT-23 package and reel packaging format. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Confirm that the single-channel configuration meets the circuit design requirements. Validate that the supply voltage constraints align with the system's power architecture.

Selection Notes

Select this component when a compact, low-power solution with rail-to-rail signal handling is required. The 7 MHz bandwidth supports moderate-speed signal processing tasks. Consider the 450 nA input bias current for impedance matching in sensor interfaces. The SOT-23 package is optimal for space-constrained portable designs where thermal dissipation remains within acceptable limits.

Part Context

The AD8517 belongs to the AD85x7 family of low-voltage operational amplifiers fabricated using Analog Devices' XFCB complementary bipolar process. This technology minimizes parasitic capacitance to enable high-speed operation at low voltages. The single-channel AD8517 complements the dual-channel AD8527, offering flexibility in multi-amplifier designs while maintaining consistent electrical characteristics across the family.

Replacement Considerations

The AD8527 serves as the dual-channel counterpart within the same family. Verify pinout compatibility if substituting with other single-channel rail-to-rail amplifiers. Ensure replacement parts match the 1.8 V to 6 V supply range and SOT-23 footprint requirements.

FAQ

Does the AD8517 exhibit phase reversal when the input signal exceeds the supply rails?

No, the AD8517 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 AD8517 can drive stably in unity gain?

In a unity gain configuration, the AD8517 can stably drive a maximum capacitive load of 400 pF.
