AD8515AKSZ-REEL7

Overview

The AD8515AKSZ-REEL7 is a single-channel, low-power CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, allowing operation from a single supply voltage ranging from 1.8 V to 5 V. The device offers a gain-bandwidth product of 5 MHz and a slew rate of 2.7 V/μs. Key electrical specifications include a maximum offset voltage of 6 mV, a typical input bias current of 2 pA, and a maximum supply current of 450 μA at 1.8 V. It operates within an extended industrial temperature range of -40°C to +125°C and is housed in a space-saving 5-lead SC-70 package.

Feature Summary

• Rail-to-rail input and output swing capability for full signal utilization near supply rails.
• Low power consumption with minimal supply current suitable for battery-operated systems.
• Robust ESD protection design capable of withstanding high electrostatic discharge voltages.
• No phase reversal occurs even when the input signal exceeds the supply voltage.

Applications

• Portable communications equipment
• Sensor interfaces
• Battery-powered devices
• PCMCIA cards

Procurement Notes

Verify the specific ordering suffix 'KS' corresponds to the 5-lead SC-70 package configuration required for your PCB layout. Confirm RoHS compliance status as indicated by the 'Z' suffix in the manufacturer's ordering guide. Ensure the reel packaging format matches your automated assembly equipment specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require both low power consumption and wide bandwidth in a compact form factor. The rail-to-rail I/O functionality makes it suitable for single-supply applications where maximizing dynamic range is critical. Consider the 5-lead SC-70 package constraints regarding thermal dissipation and physical footprint limitations during the initial schematic capture and layout phases.

Part Context

This part belongs to the AD8515 series of precision amplifiers designed for portable electronics. It shares architectural similarities with other members of the family but is distinguished by its specific SC-70 packaging and reel quantity designation. The device is optimized for applications requiring high speed-to-power ratios in constrained environments.

Replacement Considerations

Direct substitutes within the same package and pinout include AD8515ARTZ-REEL7 (SOT-23) if board space allows for package variation. Verify electrical parameter compatibility, particularly supply current and offset voltage, when considering alternative manufacturers or different package options within the same functional family.

FAQ

Does the AD8515 exhibit phase reversal when the input voltage exceeds the supply rails?

No, the AD8515 is designed with a robust input stage that prevents phase reversal even when the input signal exceeds the supply voltage by more than 0.6 V.

What is the maximum supply voltage allowed for this component?

The absolute maximum rating for the supply voltage is 6 V, although normal operation is specified up to 5 V.
