AD8515AKS-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 and operates on 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 is housed in a space-saving 5-lead SC70 package and is specified for operation over an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Rail-to-rail input and output swing capability
• Low power consumption suitable for battery-powered applications
• Space-saving 5-lead SC70 surface-mount package
• No phase reversal when input signal exceeds supply rails

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the AKSZ designation matches the intended 5-lead SC70 package dimensions for PCB layout compatibility. Ensure procurement channels provide documentation confirming RoHS compliance status as indicated by the Z suffix in official Analog Devices ordering guides.

Selection Notes

Select this component for designs requiring high precision with minimal power draw in constrained physical spaces. The rail-to-rail performance ensures maximum dynamic range in single-supply systems operating at low voltages. Consider the 5 MHz bandwidth and 2.7 V/μs slew rate for applications requiring moderate speed without excessive power dissipation. Verify that the 450 μA supply current meets the thermal and energy budget constraints of the target system.

Part Context

This part belongs to the AD8515 family of low-power CMOS operational amplifiers designed for portable electronics. The AKSZ variant specifically denotes the SC70 package option, distinguishing it from the SOT-23 (RJ) variants within the same series. The REEL7 suffix indicates the standard reel quantity packaging used for high-volume manufacturing integration.

Replacement Considerations

Direct substitutes within the same package and pinout include other AD8515 variants such as AD8515ARTZ-REEL7 for SOT-23 packages if footprint changes are permissible. Cross-family replacements must be evaluated for pin compatibility and electrical parameter alignment.
