Replacement verdict
Compatible functional replacement candidate
The AD8014ARZ and AD8013ARZ-14 are both high-speed current-feedback operational amplifiers from Analog Devices sharing a common core architecture, but they differ in channel count and package configuration. The AD8014ARZ is a single-channel amplifier in an 8-lead SOIC package, while the AD8013ARZ-14 is a triple-channel amplifier in a 14-lead SOIC package. Because the channel count and footprint differ, the AD8013ARZ-14 is not a direct drop-in replacement for the AD8014ARZ; however, for applications requiring additional channels within the same amplifier family, it represents a viable functional candidate subject to validation of the specific circuit requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD8014ARZ | AD8013ARZ-14 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 3 | Determines how many independent signal channels can be processed in one package; a single vs. triple configuration directly affects circuit architecture and board space. |
| Package / Mounting Type | 8-Lead SOIC (surface mount) | 14-Lead SOIC (surface mount) | Footprint and pin count must match the PCB layout; different packages are not drop-in compatible and require layout changes. |
| -3 dB Bandwidth | 400 MHz | 150 MHz | Sets the maximum signal frequency the amplifier can handle with acceptable gain; critical for high-speed signal chain performance. |
| Slew Rate | 4000 V/µs | 1000 V/µs | Governs how fast the output can respond to large signal steps; affects distortion and settling in pulse and video applications. |
| Supply Current per Amplifier | 1.15 mA | 1.3 mA | Impacts total power budget and thermal design; higher quiescent current reduces battery life in portable systems. |
| Input Voltage Noise | 2.5 nV/√Hz | 3.5 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal amplification; important for precision and sensor front-ends. |
| Output Current (Typical) | 50 mA | 60 mA | Determines the drive capability for loads such as cables and ADCs; affects ability to drive low-impedance loads without distortion. |
| Operating Supply Voltage Range | 4.5 V to 12 V (±2.25 V to ±6 V) | 4.5 V to 11 V (±2.25 V to ±5.5 V) | Defines the allowable power supply window; slight differences affect compatibility with existing rails and headroom margins. |
| Input Offset Voltage (Max) | 5 mV | 10 mV | DC accuracy parameter; lower offset reduces error in precision amplification and DC-coupled signal paths. |

Frequently asked questions
What are the primary differences between the AD8014ARZ and AD8013ARZ-14?
The AD8014ARZ is a single, high-speed current-feedback operational amplifier supplied in an 8-lead SOIC package. The AD8013ARZ-14 is a triple, high-speed current-feedback operational amplifier supplied in a 14-lead SOIC package. The core difference is channel count (1 vs. 3) and package pin count (8 vs. 14).
Are the AD8014ARZ and AD8013ARZ-14 pin-compatible?
No. The AD8014ARZ uses an 8-lead SOIC footprint, while the AD8013ARZ-14 uses a 14-lead SOIC footprint. The package body widths and pin counts differ, so they cannot be interchanged on the same PCB land pattern without redesign.
Do both devices share the same current-feedback architecture and bandwidth class?
Yes. Both are current-feedback operational amplifiers from the Analog Devices AD801x family, targeting high-speed signal processing. Designers should still verify the specific gain-bandwidth, slew rate, and supply current limits from each device's respective datasheet before finalizing a design.
Can the AD8013ARZ-14 replace the AD8014ARZ in a single-channel design?
Not directly. The AD8013ARZ-14 is a triple amplifier in a 14-lead package, so it is physically larger and has a different pinout. A single-channel design using the AD8014ARZ would require a PCB layout change to accommodate the 14-lead package, and unused channels on the AD8013ARZ-14 would need to be properly terminated per the datasheet.
What supply voltage ranges are specified for these amplifiers?
Both devices are specified for operation on dual supplies typically in the ±5 V range, with absolute maximum ratings and recommended operating conditions detailed in the respective Analog Devices datasheets. Always confirm the exact supply limits and decoupling requirements from the official datasheet before use.
Which device is better suited for multi-channel signal chains?
The AD8013ARZ-14 is better suited for multi-channel signal chains because it integrates three current-feedback amplifiers in one 14-lead SOIC package, reducing board space and component count compared to using three separate AD8014ARZ devices.
Are both parts RoHS-compliant and available in the same temperature grade?
Both the AD8014ARZ and AD8013ARZ-14 are offered in RoHS-compliant SOIC packages with the "Z" suffix indicating lead-free construction. Temperature grade and exact ordering codes should be verified against the Analog Devices product pages or authorized distributor listings such as DigiKey or Mouser before ordering.
