Replacement verdict
Compatible functional replacement candidate
The AD8017ARZ and AD8010AR are both dual high-speed current-feedback operational amplifiers from Analog Devices offered in the same 8-lead SOIC package, making them a plausible functional replacement candidate. However, the AD8017ARZ provides substantially higher output current drive and a different supply voltage range than the AD8010AR, so the replacement is only valid after validating load drive, supply headroom, and thermal conditions in the target application.

Key electrical and mechanical differences between the two devices
| Parameter | AD8017ARZ | AD8010AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Channel count determines whether one package can serve two signal paths; a dual and single are not drop-in substitutes in multi-channel designs. |
| -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; higher slew rate supports faster large-signal transitions. |
| Output Current (per amplifier) | 200 mA | 200 mA | Output drive capability determines the load the amplifier can drive, such as cables or low-impedance loads. |
| Supply Voltage Range | ±2.5 V to ±6 V (5 V to 12 V) | ±5 V to ±15 V (10 V to 30 V) | The allowable supply range must match the system rail voltages; incompatible ranges prevent direct substitution. |
| Supply Current (per amplifier, typical) | 7 mA | 15 mA | Quiescent current affects power budget and thermal design, especially in portable or densely packed systems. |
| Input Voltage Noise Density | 2.9 nV/√Hz | 2.5 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal amplification applications. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package footprint and pinout must match for board-level interchangeability; identical packages ease substitution. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment to ensure reliable operation. |

Frequently asked questions
What are the primary differences between the AD8017ARZ and the AD8010AR?
The AD8017ARZ is a dual, high-output-current, low-power operational amplifier optimized for driving ADSL and other high-peak-current loads, while the AD8010AR is a single, high-current, low-distortion amplifier designed for video and communication applications. The AD8017ARZ offers two amplifiers per package with a typical supply current of 7 mA per amplifier, whereas the AD8010AR is a single amplifier with a typical supply current of 15 mA.
Are the AD8017ARZ and AD8010AR pin-compatible?
No. The AD8017ARZ is supplied in an 8-lead SOIC package containing two operational amplifiers, while the AD8010AR is supplied in an 8-lead SOIC package containing a single operational amplifier with a different pinout. The pin functions and PCB land patterns differ, so they are not direct drop-in replacements.
What are the typical supply voltage ranges for these amplifiers?
The AD8017ARZ operates from a dual supply of ±2.5 V to ±6 V (or single supply of 5 V to 12 V), and the AD8010AR operates from a dual supply of ±5 V to ±6 V (or single supply of 10 V to 12 V). Designs must verify the supply range against the specific datasheet revision before substitution.
How do the output current capabilities compare?
The AD8017ARZ is specified for a high output current of typically 200 mA per amplifier, making it suitable for driving low-impedance loads such as ADSL line drivers. The AD8010AR is specified for an output current of typically 200 mA as well, but as a single amplifier it concentrates this capability in one channel rather than two.
Which device is better suited for video applications?
The AD8010AR is optimized for video and communication applications with low differential gain and phase errors and a wide bandwidth of 230 MHz, making it well suited for video line driving. The AD8017ARZ, while capable, is primarily optimized for ADSL and high-peak-current loads, so the AD8010AR is generally the preferred choice for video signal chains.
Can the AD8017ARZ replace the AD8010AR in an existing design?
Not directly. The AD8017ARZ is a dual amplifier with a different pinout, supply range, and quiescent current than the single AD8010AR. A replacement requires schematic and PCB redesign, and all parameters must be validated against the manufacturer datasheet for the target application.
What are the package and operating temperature specifications?
Both the AD8017ARZ and AD8010AR are offered in an 8-lead SOIC package and are specified for the industrial temperature range of −40°C to +85°C. Designers should confirm the exact orderable part number and temperature grade against the official Analog Devices datasheet.
