Replacement verdict
Compatible functional replacement candidate
The AD8000YRDZ and AD8002ARZ-RL are both high-speed current-feedback operational amplifiers from Analog Devices sharing a similar gain-bandwidth class, but they differ in channel count, package, and specified dynamic performance. The AD8002ARZ-RL is a dual device in an 8-lead SOIC, while the AD8000YRDZ is a single device in an 8-lead SOIC_EP with thermal pad. Designers should validate bandwidth, slew rate, and thermal behavior in the target circuit before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | AD8000YRDZ | AD8002ARZ-RL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 2 | Channel count determines how many independent signal paths can be processed; a dual amplifier can replace two singles but not vice versa in a given footprint. |
| -3 dB Bandwidth | 1.5 GHz | 600 MHz | Bandwidth sets the maximum signal frequency the amplifier can handle with acceptable gain; a large mismatch limits high-speed signal fidelity. |
| Slew Rate | 4100 V/µs | 1200 V/µs | Slew rate limits how fast the output can track large signal swings; lower slew rate causes distortion on fast, large-amplitude signals. |
| Supply Voltage Range | 4.5 V to 11 V (±2.25 V to ±5.5 V) | 6 V to 12 V (±3 V to ±6 V) | The usable supply window must cover the system rail voltages; incompatible ranges can prevent direct substitution without rail changes. |
| Input Offset Voltage (typ) | 1 mV | 2 mV | Offset voltage adds a DC error at the output; higher offset degrades precision in DC-coupled and low-level signal applications. |
| Input Voltage Noise Density | 1.6 nV/√Hz | 2 nV/√Hz | Noise density sets the noise floor for low-level signals; a higher value reduces dynamic range in sensitive front-end circuits. |
| Quiescent Supply Current per Amplifier | 14.5 mA | 7 mA | Quiescent current drives power budget and thermal load; differences affect total system power and heat dissipation. |
| Package | 8-Lead SOIC (EP) | 8-Lead SOIC | Package and pinout must match for board-level drop-in compatibility; exposed-pad variants may require different PCB thermal design. |
| Output Current (typ) | 100 mA | 70 mA | Output drive capability determines the load the amplifier can drive; lower current limits driving low-impedance or capacitive loads. |

Frequently asked questions
What are the key differences between the AD8000YRDZ and the AD8002ARZ-RL?
The AD8000YRDZ is a single, ultra-high-speed current feedback operational amplifier with a 1.5 GHz -3 dB bandwidth and 4100 V/µs slew rate, supplied in an 8-lead SOIC package with an exposed pad. The AD8002ARZ-RL is a dual current feedback amplifier with a 600 MHz -3 dB bandwidth and 1200 V/µs slew rate, supplied in an 8-lead SOIC package and delivered in tape-and-reel format. The primary differences are channel count (single vs. dual), bandwidth, slew rate, and packaging/packing format.
Are the AD8000YRDZ and AD8002ARZ-RL pin-compatible?
No. The AD8000YRDZ is a single amplifier in an 8-lead SOIC_EP package, while the AD8002ARZ-RL is a dual amplifier in a standard 8-lead SOIC package. The pin functions and exposed-pad configuration differ, so they are not drop-in replacements for each other.
Can the AD8002ARZ-RL be used as a substitute for the AD8000YRDZ in an existing design?
Not directly. The AD8002ARZ-RL provides two channels at 600 MHz bandwidth and 1200 V/µs slew rate, whereas the AD8000YRDZ provides one channel at 1.5 GHz bandwidth and 4100 V/µs slew rate. Substitution requires revalidation of bandwidth, slew rate, gain flatness, and PCB layout, and the dual device's pinout does not match the single device's footprint.
What are the typical supply voltage and quiescent current specifications for these amplifiers?
Both devices operate from dual supplies typically in the ±5 V range (or single-supply equivalents within their specified operating range). The AD8000YRDZ draws a typical quiescent supply current of approximately 14 mA per amplifier, while the AD8002ARZ-RL draws approximately 7 mA per amplifier (about 14 mA total for the dual). Designers should confirm exact limits against the respective manufacturer datasheets.
Which device is better suited for high-bandwidth video or pulse applications?
The AD8000YRDZ is better suited for the highest-bandwidth applications, offering 1.5 GHz -3 dB bandwidth and 4100 V/µs slew rate, making it appropriate for wideband video and fast pulse amplification. The AD8002ARZ-RL, with 600 MHz bandwidth and 1200 V/µs slew rate across two channels, is better suited where dual-channel signal processing is needed at moderate bandwidth.
What package and packing options distinguish the AD8000YRDZ from the AD8002ARZ-RL?
The AD8000YRDZ is supplied in an 8-lead SOIC package with an exposed thermal pad (SOIC_EP), typically in tube or tray format. The AD8002ARZ-RL is supplied in a standard 8-lead SOIC package in tape-and-reel format (the "-RL" suffix denotes reel packaging), which is suited to automated high-volume assembly.
Do both amplifiers support current feedback operation, and what does that imply for design?
Yes, both the AD8000YRDZ and AD8002ARZ-RL are current feedback operational amplifiers. Current feedback topology provides high slew rates and gain-independent bandwidth, but requires attention to feedback resistor selection and PCB layout to maintain stability; the optimal feedback resistor value differs between the two devices and must be taken from each datasheet.
