Replacement verdict
Compatible functional replacement candidate
The AD8017ARZ and AD8019AR-REEL share the same high-speed current-feedback amplifier architecture and SOIC-8 footprint, making them functionally interchangeable in many signal-chain designs. However, the AD8019AR-REEL offers higher output current and wider supply headroom, while the AD8017ARZ provides lower quiescent current per amplifier. Designers should validate thermal performance and supply-rail margins before substituting in power-sensitive or high-drive applications.

Key electrical and mechanical differences between the two devices
| Parameter | AD8017ARZ | AD8019AR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 1 | Determines how many independent amplifier channels are available in a single package, directly affecting circuit topology and channel count. |
| -3 dB Bandwidth | 160 MHz | 100 MHz | Sets the maximum signal frequency the amplifier can handle with acceptable gain, critical for high-speed signal processing. |
| Slew Rate | 1600 V/µs | 1000 V/µs | Determines how fast the output can respond to large signal changes, affecting large-signal bandwidth and distortion performance. |
| Output Current (per amplifier) | 400 mA | 200 mA | Defines the drive capability for low-impedance loads such as cables or power stages; higher current supports heavier loads. |
| Supply Voltage Range | 4.5 V to 12 V | 5 V to 12 V | Specifies the allowable power supply window; a wider range offers more flexibility in system power design. |
| Quiescent Supply Current | 14 mA | 7 mA | Affects overall power consumption and thermal budget, important for power-sensitive and thermally constrained designs. |
| Input Voltage Noise | 2.5 nV/√Hz | 1.8 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal amplification applications. |
| Package Type | 8-Lead SOIC | 8-Lead SOIC | Package footprint and thermal characteristics must match the PCB layout for drop-in compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms suitability for the target environment and ensures reliable operation across the application temperature range. |

Frequently asked questions
What are the primary differences between the AD8017ARZ and the AD8019AR-REEL?
The AD8017ARZ is a dual, high-output-current, low-power operational amplifier supplied in an 8-lead SOIC package (RoHS-compliant, tube/tray). The AD8019AR-REEL is a single, high-current, low-distortion operational amplifier supplied in an 8-lead SOIC package on a 13-inch tape-and-reel. The key differences are channel count (dual vs. single), package ordering format (tube vs. reel), and the specific datasheet parameters of each device.
Can the AD8017ARZ and AD8019AR-REEL be used interchangeably in a design?
No. The AD8017ARZ is a dual amplifier and the AD8019AR-REEL is a single amplifier, so their pinouts and channel counts differ. They are not pin-compatible or functionally interchangeable; substitution requires a full review of the circuit topology, pinout, and datasheet specifications.
What are the supply voltage ranges for these two amplifiers?
Both devices are designed for operation on dual supplies. The AD8017ARZ operates from ±2.5 V to ±6 V (5 V to 12 V total), and the AD8019AR-REEL operates from ±2.5 V to ±6 V as well. Designers should confirm the exact limits in the respective manufacturer datasheets before finalizing the supply rail.
How do the output current capabilities of the AD8017ARZ and AD8019AR-REEL compare?
Both parts are specified as high-output-current amplifiers intended for driving heavy loads. The AD8017ARZ is characterized for high output current per channel, and the AD8019AR-REEL is likewise specified for high output current. For exact guaranteed output current values, refer to the manufacturer datasheets, as the two devices are characterized under different test conditions.
What package and ordering format does each part use?
The AD8017ARZ is supplied in an 8-lead SOIC package (the "RZ" suffix indicates RoHS-compliant SOIC) in tube or tray quantities. The AD8019AR-REEL is supplied in an 8-lead SOIC package on tape-and-reel (the "REEL" suffix), which is suited to automated pick-and-place assembly. Both share the SOIC body style but differ in channel count and packaging format.
Are these amplifiers suitable for driving video or cable loads?
Both the AD8017ARZ and AD8019AR-REEL are wide-bandwidth, high-current amplifiers intended for applications such as video line driving, cable driving, and other low-distortion, high-load applications. Designers should verify bandwidth, slew rate, and distortion specifications in the datasheets against the specific signal requirements of the target system.
What are the operating temperature ranges for the AD8017ARZ and AD8019AR-REEL?
Both devices are specified for the industrial temperature range of −40 °C to +85 °C. This should be confirmed against the manufacturer datasheet for the exact grade and package ordered, as temperature specifications can vary by suffix.
Which part should be selected for a dual-channel design versus a single-channel design?
For a dual-channel signal path, the AD8017ARZ is the appropriate choice because it integrates two amplifiers in one 8-lead SOIC package, saving board space. For a single-channel signal path, the AD8019AR-REEL provides one amplifier in the same SOIC footprint and is available on tape-and-reel for high-volume automated assembly.
