Replacement verdict
Compatible functional replacement candidate
The AD8017ARZ and AD8010AR-16 are both high-speed current-feedback operational amplifiers from Analog Devices, but they differ in channel count, package footprint, and supply current. The AD8017ARZ is a dual amplifier in an 8-lead SOIC package, while the AD8010AR-16 is a single amplifier in a 16-lead SOIC package. Designers should verify pinout, board layout, and thermal considerations before substituting one for the other in an existing design.

Key electrical and mechanical differences between the two devices
| Parameter | AD8017ARZ | AD8010AR-16 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Channel count determines whether one package can serve two independent signal paths; a dual cannot directly replace a single without layout changes. |
| -3 dB Bandwidth | 160 MHz | 230 MHz | Bandwidth sets the maximum signal frequency the amplifier can pass with acceptable gain, affecting high-speed signal fidelity. |
| Slew Rate | 1600 V/µs | 800 V/µs | Slew rate limits how fast the output can respond to large signal steps, impacting distortion at high frequencies and large amplitudes. |
| Output Current (per amplifier) | 400 mA | 200 mA | Output drive capability determines the load the amplifier can drive, such as cables or low-impedance loads, without clipping. |
| Supply Voltage Range | 4.4 V to 12 V (±2.2 V to ±6 V) | 5 V to 12 V (±2.5 V to ±6 V) | The allowable supply range must match the system rail voltages; a narrower minimum may prevent operation at lower supply levels. |
| Input Voltage Noise | 3.5 nV/√Hz | 2.5 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal applications, affecting sensitivity. |
| Package / Pin Count | 8-Lead SOIC | 16-Lead SOIC | Package and pin count affect PCB footprint and pinout compatibility; different packages are not drop-in replacements. |
| Quiescent Supply Current | 14 mA (typical, both amplifiers) | 15 mA (typical) | Quiescent current impacts power budget and thermal design, especially in power-sensitive or densely packed systems. |

Frequently asked questions
What are the primary differences between the AD8017ARZ and the AD8010AR-16?
The AD8017ARZ is a dual, high-output-current, low-power operational amplifier supplied in an 8-lead SOIC package, while the AD8010AR-16 is a single, high-current, low-distortion operational amplifier supplied in a 16-lead SOIC package. The AD8017ARZ integrates two amplifiers per package, whereas the AD8010AR-16 contains one amplifier with additional pinout provisions for thermal and supply management.
Are the AD8017ARZ and AD8010AR-16 pin-compatible?
No. The AD8017ARZ uses an 8-lead SOIC (R-8) package, and the AD8010AR-16 uses a 16-lead SOIC (R-16) package. The pin counts, pin functions, and PCB land patterns differ, so they are not drop-in replacements for one another.
What are the supply voltage ranges for the AD8017ARZ and AD8010AR-16?
Both devices are specified for operation on dual supplies. The AD8017ARZ operates over a supply range of ±2.5 V to ±6 V (5 V to 12 V total), and the AD8010AR-16 operates over a supply range of ±5 V to ±6 V (10 V to 12 V total), per the respective manufacturer datasheets.
How do the output current capabilities of the AD8017ARZ and AD8010AR-16 compare?
Both amplifiers are designed for high output current. The AD8017ARZ is specified to deliver a high output current suitable for driving heavy loads such as xDSL line drivers, and the AD8010AR-16 is specified for high output current with low distortion. Designers should consult the manufacturer datasheets for the exact guaranteed output current limits under the intended supply and thermal conditions.
Which device is better suited for xDSL line driver applications?
Both the AD8017ARZ and AD8010AR-16 are marketed by Analog Devices for xDSL and other high-current driver applications. The AD8017ARZ offers two amplifiers in one 8-lead package, which can suit differential driver topologies with a smaller footprint, while the AD8010AR-16 provides a single amplifier in a 16-lead package with a pinout optimized for thermal and supply handling. Selection depends on channel count, board space, and thermal requirements.
Do the AD8017ARZ and AD8010AR-16 have the same bandwidth and slew rate specifications?
No. The two devices have different dynamic specifications. The AD8017ARZ is specified with a −3 dB bandwidth and slew rate appropriate to its dual low-power design, while the AD8010AR-16 is specified with its own bandwidth and slew rate figures. Because the values differ, each must be verified against its own datasheet for the target application.
Can the AD8017ARZ and AD8010AR-16 be used interchangeably in an existing PCB design?
No. Because the packages (8-lead SOIC vs 16-lead SOIC), pinouts, channel counts, and supply ranges differ, the two devices are not interchangeable without a PCB redesign and revalidation of the circuit against the manufacturer datasheets.
