Replacement verdict
Compatible functional replacement candidate
The AD8052ARZ and AD8051AR are dual and single high-speed voltage-feedback op amps from the same AD805x family, sharing identical supply range, bandwidth class, and SOIC-8 footprint family. The AD8052ARZ is a functional replacement candidate for the AD8051AR in applications where a second channel is acceptable, but the differing channel count and quiescent current require validation against the target design.

Key electrical and mechanical differences between the two devices
| Parameter | AD8052ARZ | AD8051AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Channel count determines whether the part can serve multi-channel signal chains; a dual cannot directly replace a single in a one-channel layout without unused amplifier considerations. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Both share the same 8-lead SOIC footprint, but pinouts differ between single and dual devices, so board-level substitution requires pinout verification. |
| -3 dB Bandwidth | 110 MHz (G = +1) | 110 MHz (G = +1) | Bandwidth sets the maximum signal frequency the amplifier can pass with acceptable gain; matching values support similar high-speed signal handling. |
| Slew Rate | 145 V/µs | 145 V/µs | Slew rate limits large-signal transient response; identical slew rates mean comparable behavior for fast edges and pulse applications. |
| Supply Voltage Range | 3 V to 12 V (single) / ±1.5 V to ±6 V (dual) | 3 V to 12 V (single) / ±1.5 V to ±6 V (dual) | Supply range determines compatibility with the system rail; matching ranges allow use in the same power architecture. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Offset voltage affects DC accuracy; equal maximum offset means similar error contribution in precision signal paths. |
| Quiescent Supply Current per Amplifier | ~5.5 mA per amplifier | ~5.5 mA per amplifier | Quiescent current impacts power budget; per-amplifier matching means total power scales with channel count. |
| Output Current | ~50 mA | ~50 mA | Output drive capability determines ability to drive loads such as cables or ADC inputs; matching values support similar load driving. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Temperature range confirms suitability for industrial environments; identical ratings allow use in the same thermal conditions. |

Frequently asked questions
What are the primary differences between the AD8052ARZ and the AD8051AR?
The AD8052ARZ is a dual, low-power, high-speed voltage feedback operational amplifier, while the AD8051AR is a single, low-power, high-speed voltage feedback operational amplifier. The AD8052ARZ contains two amplifiers in one package, whereas the AD8051AR contains one amplifier. Both are fabricated on Analog Devices' proprietary XFCB process and offer similar per-amplifier AC performance, but the AD8052ARZ is supplied in an 8-lead SOIC package and the AD8051AR is supplied in an 8-lead SOIC package as well, with different pinouts reflecting single versus dual configurations.
Are the AD8052ARZ and AD8051AR pin-compatible?
No. The AD8052ARZ is a dual amplifier with both amplifiers' inputs and outputs assigned across the 8-lead SOIC pinout, while the AD8051AR is a single amplifier that uses the same 8-lead SOIC footprint for one amplifier plus power and optional disable pins. Because the pin functions differ, they cannot be dropped into the same PCB land pattern without redesign.
What are the key AC specifications of the AD8052ARZ and AD8051AR?
Both devices offer a -3 dB bandwidth of approximately 110 MHz (G = +1) and a slew rate of approximately 145 V/µs per amplifier, with 0.1% settling time of about 50 ns. These parameters are specified per amplifier and are essentially identical between the single AD8051AR and each amplifier in the dual AD8052ARZ, since both use the same core amplifier design.
What are the supply voltage and power consumption characteristics of these amplifiers?
Both the AD8052ARZ and AD8051AR operate from a single supply of +3 V to +12 V or a dual supply of ±1.5 V to ±6 V. Each amplifier typically draws approximately 5.5 mA of supply current, making them suitable for low-power, high-speed signal chain applications. The dual AD8052ARZ therefore draws roughly twice the total quiescent current of the single AD8051AR when both amplifiers are active.
Can the AD8051AR be used as a replacement for one channel of the AD8052ARZ in an existing design?
Functionally, one channel of the AD8052ARZ and the AD8051AR share the same amplifier core and similar AC/DC specifications, so the AD8051AR can serve as a single-channel equivalent. However, because the package pinouts differ, a direct drop-in replacement on the same PCB is not possible; the board layout must be revised to accommodate the single-amplifier pinout.
What are the input voltage noise and offset voltage specifications for these parts?
Both the AD8052ARZ and AD8051AR specify an input voltage noise density of approximately 6 nV/√Hz at 100 kHz and a typical input offset voltage of about 1 mV (5 mV maximum). These matched specifications reflect the shared amplifier core and make both devices suitable for precision high-speed signal conditioning.
In which applications are the AD8052ARZ and AD8051AR typically used?
Both amplifiers are commonly used in video line drivers, active filters, ADC input buffers, CCD imaging front ends, and portable instrumentation where low power and high speed are required. The AD8052ARZ is preferred where two matched amplifiers are needed in a compact footprint, while the AD8051AR is used in single-channel signal paths to minimize board space and power.
