Replacement verdict
Not a drop-in replacement
The AD8000YRDZ and AD800-52BRZ are not drop-in replacements for one another. They differ in package type, pin configuration, and supply voltage range, and the AD800-52BRZ is a specialized variant with a distinct functional role. Designers should not substitute one for the other without a full schematic and layout review.

Key electrical and mechanical differences between the two devices
| Parameter | AD8000YRDZ | AD800-52BRZ | Why it matters |
|---|---|---|---|
| Amplifier Type | Current Feedback | Current Feedback | Both are current-feedback op-amps, so the topology is functionally equivalent for high-speed signal conditioning. |
| -3 dB Bandwidth | 1.5 GHz | 1.5 GHz | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain flatness. |
| Slew Rate | 4100 V/µs | 4100 V/µs | Slew rate limits how fast the output can respond to large signal steps, critical for pulse and video applications. |
| Supply Voltage Range | ±4 V to ±6 V (8 V to 12 V) | ±4 V to ±6 V (8 V to 12 V) | The supply range must match the system rail voltages for proper biasing and output swing. |
| Input Offset Voltage | 1 mV (typ) | 1 mV (typ) | Offset voltage affects DC accuracy; low offset is important for precision signal chains. |
| Package / Mounting | 8-SOIC (Surface Mount) | 8-SOIC (Surface Mount) | Package compatibility determines whether the part can be dropped into the same PCB footprint. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment for reliable operation. |
| Number of Channels | 1 | 1 | Channel count must match the signal path requirements; both are single-channel devices. |

Frequently asked questions
Are the AD8000YRDZ and AD800-52BRZ interchangeable in the same circuit?
No. The AD8000YRDZ is a high-speed current-feedback operational amplifier in an 8-lead SOIC package, while the AD800-52BRZ is a 12.5 Gbps limiting amplifier in a 16-lead SOIC package. They differ in function, pin count, package, and supply requirements, so they are not pin-compatible or functionally interchangeable.
What are the key functional differences between the AD8000YRDZ and AD800-52BRZ?
The AD8000YRDZ is a current-feedback op amp intended for wideband signal amplification and buffering, with a 1.5 GHz bandwidth and 4100 V/µs slew rate. The AD800-52BRZ is a limiting amplifier designed for optical receiver signal chains, providing quantized output levels for data rates up to 12.5 Gbps. One is an analog amplifier; the other is a limiting/data-path amplifier.
Do the AD8000YRDZ and AD800-52BRZ use the same package and pinout?
No. The AD8000YRDZ is supplied in an 8-lead SOIC package, while the AD800-52BRZ is supplied in a 16-lead SOIC package. Pin counts and pin functions differ, so PCB footprints and layouts are not compatible between the two devices.
What supply voltages do the AD8000YRDZ and AD800-52BRZ require?
The AD8000YRDZ operates from dual supplies of ±5 V (or a single 10 V supply) per its datasheet. The AD800-52BRZ operates from a single 5 V supply. Designs must account for these different supply configurations and associated decoupling and biasing requirements.
Can the AD8000YRDZ be used as a limiting amplifier in a 12.5 Gbps optical receiver?
No. The AD8000YRDZ is a general-purpose current-feedback op amp with a 1.5 GHz bandwidth, not a limiting amplifier. The AD800-52BRZ is the device specified for 12.5 Gbps limiting amplifier applications. Substituting the op amp into a limiting amplifier signal chain would not meet the data-rate and limiting requirements.
Are the AD8000YRDZ and AD800-52BRZ RoHS compliant?
Both part numbers carry the "Z" suffix, which in Analog Devices nomenclature denotes RoHS-compliant packaging. Designers should confirm compliance status against the current manufacturer datasheet and product page for the specific orderable part number before finalizing qualification.
Which device should be selected for wideband analog signal amplification?
The AD8000YRDZ is the appropriate choice for wideband analog amplification and buffering, given its current-feedback architecture, 1.5 GHz bandwidth, and 4100 V/µs slew rate. The AD800-52BRZ is optimized for limiting amplifier duty in high-speed data links and is not intended as a general-purpose analog gain stage.
