Replacement verdict
Compatible functional replacement candidate
The AD8051ARZ and AD8052AR are both high-speed voltage-feedback operational amplifiers from the same Analog Devices AD805x family, sharing identical supply voltage ranges, bandwidth class, and SOIC-8 footprint. The AD8051ARZ is a single-channel device with a disable feature, while the AD8052AR is a dual-channel device without disable, so the primary functional difference is channel count and power-down capability. Designers substituting between them must account for the additional amplifier channel and the absence of a disable pin on the AD8052AR, but core AC and DC performance characteristics remain closely aligned.

Key electrical and mechanical differences between the two devices
| Parameter | AD8051ARZ | AD8052AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 2 | Determines how many independent signal channels the package provides; a dual amplifier cannot directly replace a single in a single-channel layout without unused channels. |
| Package / Mounting Type | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Both share the same 8-lead SOIC footprint, but pinout differs due to channel count, affecting board-level drop-in compatibility. |
| -3 dB Bandwidth | 110 MHz | 110 MHz | Sets the maximum usable signal frequency; matching bandwidth supports similar high-speed signal handling. |
| Slew Rate | 140 V/µs | 140 V/µs | Governs how fast the output can respond to large signal swings; identical slew rate preserves transient performance. |
| 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) | Defines the allowable power supply; matching ranges allow use in the same supply rails. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Affects DC accuracy; equal offset specs mean comparable precision in DC-coupled applications. |
| Quiescent Supply Current per Amplifier | 4.8 mA typ | 4.8 mA typ | Impacts power budget; identical per-amplifier current keeps power consumption predictable. |
| Output Current | 50 mA | 50 mA | Determines drive capability for loads; matching output current supports similar load driving. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Specifies environmental limits; identical ranges ensure equivalent thermal robustness. |

Frequently asked questions
What are the key differences between the AD8051ARZ and AD8052AR?
The AD8051ARZ is a single, high-speed, voltage-feedback operational amplifier, while the AD8052AR is a dual version of the same amplifier family. Both offer a 3 dB bandwidth of 110 MHz and a slew rate of 145 V/µs, but the AD8051ARZ comes in an 8-lead SOIC package and the AD8052AR comes in an 8-lead SOIC package housing two independent amplifiers.
Are the AD8051ARZ and AD8052AR pin-compatible?
No. The AD8051ARZ is a single amplifier in an 8-lead SOIC package, while the AD8052AR is a dual amplifier in an 8-lead SOIC package. The pinouts differ because the dual device uses the same package footprint to accommodate two amplifiers, so they cannot be interchanged without verifying the pin functions against the respective datasheets.
What is the supply voltage range for the AD8051ARZ and AD8052AR?
Both devices operate from a single supply of 3 V to 12 V or a dual supply of ±1.5 V to ±6 V. This flexibility makes them suitable for portable and battery-powered applications as well as systems using standard ±5 V rails.
Can the AD8052AR be used as a drop-in replacement for the AD8051ARZ in an existing single-amplifier design?
No, not as a direct drop-in replacement. The AD8052AR contains two amplifiers in an 8-lead package with a different pinout than the single AD8051ARZ. A redesign of the PCB layout and verification of pin functions against the AD8052AR datasheet are required before substitution.
What are the typical applications for the AD8051ARZ and AD8052AR?
Both amplifiers are suited for high-speed signal processing, video and imaging systems, active filters, ADC drivers, and portable instrumentation. The AD8051ARZ is preferred where a single amplifier is needed, while the AD8052AR is used where two matched amplifiers in one package are required to save board space.
Do the AD8051ARZ and AD8052AR have the same bandwidth and slew rate specifications?
Yes. Both the AD8051ARZ and AD8052AR are specified with a -3 dB bandwidth of 110 MHz and a slew rate of 145 V/µs, as stated in the Analog Devices datasheets. The core amplifier performance is identical; the difference is the number of amplifiers per package.
What is the operating temperature range for the AD8051ARZ and AD8052AR?
Both devices are specified for operation over the industrial temperature range of -40°C to +85°C, making them suitable for industrial and commercial applications requiring reliable performance across a wide temperature span.
