Replacement verdict
Compatible functional replacement candidate
The AD8017ARZ and AD8013ARZ-14 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 AD8013ARZ-14 is a triple amplifier in a 14-lead SOIC package. Because the channel count and pinout differ, the AD8013ARZ-14 is not a direct drop-in replacement for the AD8017ARZ; however, for applications where a third channel is acceptable and board space permits, it can serve as a functional substitute. Designers should verify supply current, output drive, and thermal performance against the target application before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8017ARZ | AD8013ARZ-14 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 3 | Channel count determines how many independent signal paths can be processed; a dual cannot directly replace a triple in multi-channel designs. |
| -3 dB Bandwidth | 160 MHz | 150 MHz | Bandwidth sets the maximum signal frequency the amplifier can handle with acceptable gain, affecting video and high-speed signal fidelity. |
| Slew Rate | 1600 V/µs | 1000 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 | 30 mA | Output drive capability determines the load the amplifier can drive; the higher-current part suits line-driving and low-impedance loads. |
| Supply Voltage Range | ±2.5 V to ±6 V (5 V to 12 V) | ±2.5 V to ±5.5 V (5 V to 11 V) | The allowable supply range must cover the system rail voltages; a narrower range may restrict use in higher-voltage designs. |
| Quiescent Supply Current | 11 mA typ | 12 mA typ | Quiescent current affects power budget and thermal load, which matters in power-sensitive or densely packed systems. |
| Input Voltage Noise | 2.5 nV/√Hz | 3.5 nV/√Hz | Lower input voltage noise improves signal-to-noise ratio in low-level signal amplification applications. |
| Package | 8-Lead SOIC | 14-Lead SOIC | Package footprint and pin count must match the PCB layout; different packages are not drop-in compatible. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range confirms suitability for industrial environments; identical ranges mean equivalent thermal applicability. |

Frequently asked questions
What are the primary differences between the AD8017ARZ and AD8013ARZ-14?
The AD8017ARZ is a dual, high-output-current, low-distortion operational amplifier supplied in an 8-lead SOIC package, while the AD8013ARZ-14 is a triple, low-power, high-speed amplifier supplied in a 14-lead SOIC package. The AD8017ARZ is optimized for driving heavy loads with high output current, whereas the AD8013ARZ-14 provides three independent amplifiers in a single package for multi-channel signal processing.
Are the AD8017ARZ and AD8013ARZ-14 pin-compatible?
No. The AD8017ARZ uses an 8-lead SOIC (R-8) package, and the AD8013ARZ-14 uses a 14-lead SOIC (R-14) package. The pin counts, pin assignments, and package footprints differ, so they are not drop-in replacements for each other.
How do the supply voltage ranges of the AD8017ARZ and AD8013ARZ-14 compare?
Both devices are specified for operation on dual supplies of ±2.5 V to ±6 V (or single supplies of 5 V to 12 V), per the Analog Devices datasheets. Designers should verify the exact supply range and derating requirements against the latest official datasheet for each part before finalizing a design.
Which device is better suited for driving heavy capacitive or low-impedance loads?
The AD8017ARZ is specifically designed as a high-output-current amplifier capable of delivering substantial output current, making it suitable for driving heavy loads such as video cables and low-impedance lines. The AD8013ARZ-14 is a low-power, high-speed triple amplifier intended for multi-channel applications where per-channel power consumption is a priority rather than high output drive.
Can the AD8013ARZ-14 replace the AD8017ARZ in an existing dual-amplifier design?
Not directly. The AD8013ARZ-14 contains three amplifiers in a 14-lead package, while the AD8017ARZ contains two amplifiers in an 8-lead package. A replacement would require PCB redesign to accommodate the different package, pinout, and channel count, and the electrical performance must be re-validated against the application requirements.
What are the typical applications for each device?
The AD8017ARZ is typically used in applications requiring high output current and low distortion, such as xDSL line drivers, video distribution, and cable drivers. The AD8013ARZ-14 is typically used in multi-channel video processing, RGB signal amplification, and other applications benefiting from three matched high-speed amplifiers in one package.
Do both parts operate over the industrial temperature range?
Both the AD8017ARZ and AD8013ARZ-14 are specified for the industrial temperature range of −40°C to +85°C, as stated in their respective Analog Devices datasheets. Always confirm the exact temperature grade and specifications from the current official datasheet before use in a design.
