Replacement verdict
Compatible functional replacement candidate
The AD8013ARZ-14 is a viable functional replacement candidate for the AD8012ARZ in multi-channel current-feedback amplifier applications, sharing the same core amplifier architecture and supply requirements. However, the differing channel count and package footprint require layout validation before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8012ARZ | AD8013ARZ-14 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (dual) | 3 (triple) | Channel count determines how many independent signal paths can be processed; a dual cannot directly replace a triple in multi-channel designs. |
| Package / Pin Count | 8-Lead SOIC | 14-Lead SOIC | Different package footprints and pinouts prevent drop-in board substitution without layout changes. |
| -3 dB Bandwidth | 350 MHz | 330 MHz | Bandwidth sets the maximum signal frequency the amplifier can handle with acceptable gain; similar values indicate comparable high-speed capability. |
| Slew Rate | 2250 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 transient response. |
| Supply Voltage Range | ±1.5 V to ±6 V (3 V to 12 V) | ±1.5 V to ±6 V (3 V to 12 V) | Matching supply ranges allow both parts to operate in the same power environment, easing substitution. |
| Supply Current per Amplifier | 1.2 mA typ | 1.3 mA typ | Quiescent current affects power budget and thermal design; comparable values mean similar power consumption per channel. |
| Input Voltage Noise | 2.5 nV/√Hz | 2.5 nV/√Hz | Low input noise is critical for small-signal and high-dynamic-range applications; identical noise performance supports equivalent signal fidelity. |
| Output Current | 125 mA | 125 mA | Output drive capability determines the load the amplifier can drive; matching values indicate equivalent load-driving ability. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure both parts suit the same environmental conditions and reliability requirements. |

Frequently asked questions
What are the primary differences between the AD8012ARZ and AD8013ARZ-14?
The AD8012ARZ is a dual, low-power, high-speed current feedback amplifier supplied in an 8-lead SOIC package, while the AD8013ARZ-14 is a triple, low-power, high-speed current feedback amplifier supplied in a 14-lead SOIC package. The AD8012ARZ integrates two amplifiers, whereas the AD8013ARZ-14 integrates three amplifiers, making the latter suitable for RGB or three-channel signal processing applications.
Are the AD8012ARZ and AD8013ARZ-14 pin-compatible?
No. The AD8012ARZ uses an 8-lead SOIC package, and the AD8013ARZ-14 uses a 14-lead SOIC package. The pin counts, pin assignments, and package footprints differ, so they are not drop-in replacements for each other on the same PCB land pattern.
Do both amplifiers share the same bandwidth and slew rate specifications?
Both devices are current feedback amplifiers from the same Analog Devices product family and share similar high-speed performance characteristics. However, the AD8012ARZ is specified as a dual amplifier and the AD8013ARZ-14 as a triple amplifier, so designers should consult the respective manufacturer datasheets for the exact -3 dB bandwidth, slew rate, and gain flatness values for each part before finalizing a design.
What are the typical supply voltage and power consumption considerations for these parts?
Both the AD8012ARZ and AD8013ARZ-14 are low-power current feedback amplifiers intended for operation from ±5 V or single-supply configurations within the manufacturer-specified range. Because the AD8013ARZ-14 contains three amplifiers versus two in the AD8012ARZ, total quiescent current for the triple device is higher. Exact supply current and voltage range values should be verified from the official Analog Devices datasheets.
Which part should be selected for a three-channel video or RGB application?
The AD8013ARZ-14 is the appropriate choice for three-channel applications such as RGB video processing because it integrates three current feedback amplifiers in a single 14-lead SOIC package. The AD8012ARZ, being a dual amplifier, would require an additional amplifier channel or a second package to handle three channels.
Can the AD8012ARZ be used as a substitute for the AD8013ARZ-14 in an existing design?
No, not as a direct substitute. The AD8012ARZ provides only two amplifier channels and uses an 8-lead SOIC footprint, while the AD8013ARZ-14 provides three channels in a 14-lead SOIC footprint. Substitution would require a PCB redesign to accommodate the different package and channel count, and the design's channel requirements must be re-evaluated.
Are both devices available in the same temperature grade and packaging option?
Both the AD8012ARZ and AD8013ARZ-14 are offered in SOIC surface-mount packages with the "Z" suffix indicating RoHS-compliant, lead-free construction per Analog Devices nomenclature. The AD8012ARZ is in an 8-lead SOIC and the AD8013ARZ-14 is in a 14-lead SOIC. Designers should confirm the exact operating temperature range and ordering codes from the official Analog Devices datasheets and distributor listings.
