Replacement verdict
Compatible functional replacement candidate
The AD8014ARZ and AD8010AR-REEL are both high-speed current-feedback operational amplifiers from Analog Devices in the same 8-lead SOIC package, sharing a comparable supply voltage range and similar bandwidth class. However, they differ in key electrical characteristics such as quiescent current, output drive capability, and specified dynamic performance, so the AD8010AR-REEL can serve as a functional candidate only after the circuit's load, power budget, and AC requirements are validated against the AD8014ARZ specifications.

Key electrical and mechanical differences between the two devices
| Parameter | AD8014ARZ | AD8010AR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | Current Feedback | Current Feedback | Both are current-feedback op-amps, so the topology is compatible for high-speed signal-chain substitution. |
| -3 dB Bandwidth | 400 MHz | 230 MHz | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain flatness. |
| Slew Rate | 4000 V/µs | 800 V/µs | Slew rate limits large-signal transient response and distortion at high frequencies. |
| Output Current (Typical) | 50 mA | 200 mA | Output drive capability determines whether the part can drive low-impedance loads such as cables or ADSL lines. |
| Supply Voltage Range | ±4.5 V to ±6 V (9 V to 12 V) | ±5 V to ±15 V (10 V to 30 V) | The supply range must match the system rail voltages for the part to operate within specification. |
| Supply Current per Amplifier | 1.1 mA | 15 mA | Quiescent current affects power budget and thermal design, especially in multi-channel or portable systems. |
| Input Voltage Noise | 2.5 nV/√Hz | 2.5 nV/√Hz | Input noise sets the noise floor for low-level signal amplification and affects SNR. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package compatibility ensures the part can be placed on the same PCB footprint. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment for reliable operation. |

Frequently asked questions
What are the primary differences between the AD8014ARZ and AD8010AR-REEL?
The AD8014ARZ is a single, low-power, high-speed current-feedback operational amplifier supplied in an 8-lead SOIC package, while the AD8010AR-REEL is a triple, high-output-current video operational amplifier supplied in a 14-lead SOIC package on tape and reel. The AD8014ARZ is optimized for low power consumption (approximately 1.3 mA supply current per amplifier) and high slew rate, whereas the AD8010AR-REEL is designed to drive heavy video loads with high output current (approximately 200 mA per amplifier) and includes three amplifiers in one package.
Are the AD8014ARZ and AD8010AR-REEL pin-compatible or interchangeable?
No. The AD8014ARZ is an 8-lead SOIC single amplifier, and the AD8010AR-REEL is a 14-lead SOIC triple amplifier. They differ in package pin count, pinout, and channel count, so they are not pin-compatible and cannot be used as drop-in replacements for one another without a PCB redesign.
What are the supply voltage ranges for the AD8014ARZ and AD8010AR-REEL?
The AD8014ARZ operates from a single supply of +4.5 V to +12 V or a dual supply of ±2.25 V to ±6 V. The AD8010AR-REEL operates from a dual supply of ±5 V to ±15 V (or corresponding single-supply ranges). Designers should verify the exact supply limits against the respective Analog Devices datasheets before finalizing the power supply design.
Which part is better suited for low-power portable applications?
The AD8014ARZ is better suited for low-power portable applications. It draws approximately 1.3 mA of supply current per amplifier, whereas the AD8010AR-REEL is a higher-power triple amplifier intended for driving heavy video loads and draws substantially more supply current per amplifier. The AD8014ARZ's lower quiescent current makes it preferable where power budget is critical.
Which part is intended for video line-driving applications?
The AD8010AR-REEL is specifically designed for video line-driving applications. It is a triple operational amplifier with high output current capability (approximately 200 mA per amplifier) and is optimized to drive multiple video loads, making it suitable for RGB video distribution and cable driving. The AD8014ARZ is a single low-power amplifier and is not specified for the same heavy video load-driving role.
What are the package and packaging differences between the two parts?
The AD8014ARZ is supplied in an 8-lead SOIC package (the "RZ" suffix indicates RoHS-compliant SOIC). The AD8010AR-REEL is supplied in a 14-lead SOIC package and is delivered on tape and reel ("REEL" suffix), which is suited to automated high-volume assembly. The difference in lead count (8 vs. 14) reflects the single-amplifier versus triple-amplifier configuration.
Can the AD8014ARZ replace one channel of the AD8010AR-REEL in an existing design?
Not directly. Although both are current-feedback-style high-speed amplifiers from Analog Devices, they differ in package pinout, supply range, output current capability, and channel count. Replacing one channel of an AD8010AR-REEL with an AD8014ARZ would require verifying supply voltages, feedback network values, load driving requirements, and PCB layout against both datasheets. A direct substitution without this validation is not supported.
Are both parts RoHS compliant?
The AD8014ARZ carries the "Z" suffix, which denotes RoHS-compliant packaging per Analog Devices nomenclature. For the AD8010AR-REEL, RoHS status should be confirmed against the specific ordering code and the manufacturer's datasheet or product page, as the "REEL" suffix denotes tape-and-reel packaging rather than RoHS status. Designers should verify compliance for the exact orderable part number before production.
