AD8515ART-REEL

Overview

The AD8515ART-REEL is a single-channel, low-power CMOS operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.8 V to 5 V and features rail-to-rail input and output swing capabilities. 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 5-lead SOT-23 package and is specified for operation across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capability allows full signal swing within the supply voltage limits.
• Low power consumption design suitable for battery-operated applications with minimal current draw.
• Space-saving 5-lead SOT-23 package enables placement close to sensors to reduce noise pickup.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. The ARTZ designation indicates the SOT-23 package. Ensure compatibility with the required tape and reel format for automated assembly processes. Confirm RoHS compliance status if environmental regulations apply to the manufacturing site. Cross-reference the manufacturer part number with distributor catalogs to ensure availability and correct revision levels.

Selection Notes

Select this component when a single-supply, low-voltage operational amplifier is required for portable systems. The rail-to-rail I/O feature is critical for maximizing dynamic range in low-voltage environments. Consider the 5 MHz bandwidth and 2.7 V/μs slew rate for signal processing tasks requiring moderate speed. The low supply current makes it appropriate for extending battery life in handheld devices compared to higher power alternatives.

Part Context

The AD8515 belongs to the Analog Devices family of low-power CMOS operational amplifiers designed for single-supply operation. It utilizes a complementary PMOS and NMOS input stage to achieve rail-to-rail performance without phase reversal. The device is fabricated using 0.6 micron CMOS technology to optimize the power-to-speed ratio. It is intended for applications where space constraints and low power consumption are primary design drivers.

Replacement Considerations

The AD8515AKSZ variants offer the same electrical characteristics but utilize the SC70 package instead of SOT-23. Verify pinout compatibility and thermal resistance differences when substituting between package types. No other direct functional replacements are documented in the provided datasheet.

FAQ

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

No, the AD8515 does not exhibit phase reversal even when the input signal exceeds the supply voltage by more than 0.6 V.

What is the maximum input bias current specification for the AD8515?

The maximum input bias current is 30 pA at 1.8 V and 5.0 V supply voltages, increasing to 8 nA at the upper temperature limit of +125°C.
