Replacement verdict
Compatible functional replacement candidate
The AD8000YRDZ and AD8002AR 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 supply headroom. The AD8002AR is a dual device in an 8-lead SOIC, while the AD8000YRDZ is a single device in an 8-lead SOIC_EP with exposed pad. Designers should validate channel count, thermal layout, and supply voltage margins before substituting one for the other in a given circuit.

Key electrical and mechanical differences between the two devices
| Parameter | AD8000YRDZ | AD8002AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 2 | Determines how many independent signal channels are available in a single package, directly affecting circuit architecture and board space. |
| -3 dB Bandwidth | 1.5 GHz | 600 MHz | Sets the maximum frequency range the amplifier can handle with acceptable gain, critical for high-speed signal processing. |
| Slew Rate | 4100 V/µs | 1200 V/µs | Governs how fast the output can respond to large signal swings, impacting large-signal bandwidth and distortion performance. |
| Supply Voltage Range | 4.5 V to 12 V | ±5 V to ±6 V (10 V to 12 V total) | Defines the allowable power supply, affecting compatibility with system rails and output signal headroom. |
| Input Offset Voltage (max) | 5 mV | 3 mV | A lower offset reduces DC error at the output, important for precision and DC-coupled applications. |
| Package Type | 8-Lead SOIC (RD) | 8-Lead SOIC (R) | Package footprint and thermal characteristics affect PCB layout and drop-in compatibility. |
| Quiescent Supply Current | 14 mA | 11 mA | Affects power consumption and thermal budget, relevant for power-sensitive designs. |
| Output Current | 100 mA | 70 mA | Determines the drive capability for loads such as cables or ADCs, impacting signal integrity under load. |

Frequently asked questions
What are the key differences between the AD8000YRDZ and the AD8002AR?
The AD8000YRDZ is a single, ultra-high-speed current feedback amplifier with a 1.5 GHz -3 dB bandwidth and 4100 V/µs slew rate, supplied in an 8-lead SOIC package (RDZ suffix). The AD8002AR 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. The primary differences are channel count (single vs. dual), bandwidth, slew rate, and quiescent current per amplifier.
Are the AD8000YRDZ and AD8002AR pin-compatible?
No. The AD8000YRDZ is a single amplifier in an 8-lead SOIC, while the AD8002AR is a dual amplifier in an 8-lead SOIC. Their pinouts differ because the dual device uses the package pins for two independent amplifier channels, so they cannot be interchanged without PCB redesign.
Can the AD8002AR be used as a drop-in replacement for the AD8000YRDZ?
No. Beyond the pinout mismatch, the AD8002AR has lower bandwidth (600 MHz vs. 1.5 GHz) and lower slew rate (1200 V/µs vs. 4100 V/µs) than the AD8000YRDZ. A replacement requires verifying gain flatness, settling time, and stability against the application requirements using the respective datasheets.
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. The AD8000YRDZ draws approximately 14 mA quiescent current for its single amplifier, while the AD8002AR draws approximately 12 mA total for both amplifiers (about 6 mA per amplifier), based on Analog Devices datasheet values.
Which device is better suited for high-speed signal chains requiring the widest bandwidth?
The AD8000YRDZ is better suited for the widest bandwidth requirements, offering a 1.5 GHz -3 dB bandwidth and 4100 V/µs slew rate, making it appropriate for high-speed video, ADC driving, and pulse applications. The AD8002AR, with 600 MHz bandwidth, is more appropriate for dual-channel applications where moderate speed and lower per-channel power are priorities.
Do both parts support the same operating temperature range?
Both the AD8000YRDZ and AD8002AR are specified for the industrial temperature range of -40°C to +85°C per their Analog Devices datasheets. Designers should still confirm the exact grade and package thermal characteristics for their specific application.
What package and mounting type do these components use?
Both the AD8000YRDZ and AD8002AR are offered in 8-lead SOIC packages with surface-mount termination. The AD8000YRDZ uses the RDZ (SOIC) suffix, and the AD8002AR uses the AR (SOIC) suffix, both suitable for standard SMT assembly processes.
