Replacement verdict
Compatible functional replacement candidate
The AD8052AR and AD8051AR-REEL are dual and single high-speed voltage-feedback operational amplifiers from the same AD805x family, sharing identical supply voltage range, bandwidth class, and SOIC-8 package footprint. The AD8052AR is a functional replacement candidate for the AD8051AR-REEL in applications where a second amplifier channel is acceptable, but the differing channel count and quiescent current require design validation before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8052AR | AD8051AR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (dual) | 1 (single) | Channel count determines whether the part can replace a single or dual op-amp in a given circuit layout; they are not drop-in substitutes. |
| -3 dB Bandwidth | 80 MHz | 110 MHz | Bandwidth sets the maximum signal frequency the amplifier can handle with acceptable gain, affecting high-speed signal fidelity. |
| Slew Rate | 140 V/µs | 170 V/µs | Slew rate limits how fast the output can respond to large signal steps; higher slew rate supports faster large-signal transitions. |
| Supply Current per Amplifier | 5.5 mA typ | 5.5 mA typ | Quiescent current affects power budget; per-amplifier values are similar, but total device current differs with channel count. |
| Input Voltage Noise | 16 nV/√Hz | 16 nV/√Hz | Input noise density impacts the signal-to-noise ratio in low-level signal applications; matching values indicate similar noise performance. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package footprint and pinout must match for board-level compatibility; identical packages ease layout reuse. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | Operating supply range determines compatibility with the system power rail and headroom for signal swing. |
| Output Current | 30 mA | 30 mA | Output drive capability affects the ability to drive loads such as cables or capacitive loads without distortion. |

Frequently asked questions
What are the key differences between the AD8052AR and AD8051AR-REEL?
The AD8052AR is a dual, low-power, high-speed voltage feedback amplifier supplied in an 8-lead SOIC package, while the AD8051AR-REEL is a single, low-power, high-speed voltage feedback amplifier in an 8-lead SOIC package supplied on tape and reel. The primary differences are channel count (dual vs. single) and packaging format (tube/tray vs. tape and reel).
Are the AD8052AR and AD8051AR-REEL pin-compatible?
No. The AD8052AR is a dual amplifier with both channels' inputs and outputs assigned across the 8-lead SOIC pinout, whereas the AD8051AR-REEL is a single amplifier using a different pin assignment on the same 8-lead SOIC footprint. They are not drop-in replacements for each other.
Do the AD8052AR and AD8051AR-REEL share the same supply voltage range?
Yes. Both devices are specified for operation from a single supply of +3 V to +12 V or a dual supply of ±1.5 V to ±6 V, consistent with the Analog Devices AD8051/AD8052/AD8054 family datasheet.
How does the bandwidth of the AD8052AR compare with the AD8051AR-REEL?
Both devices are members of the same high-speed amplifier family and share comparable AC performance, with a −3 dB bandwidth of approximately 110 MHz (G = +1) per the Analog Devices AD8051/AD8052/AD8054 datasheet. The dual AD8052AR integrates two such amplifiers in one package.
What is the significance of the "-REEL" suffix on the AD8051AR-REEL?
The "-REEL" suffix indicates the device is supplied in tape-and-reel packaging intended for automated pick-and-place assembly, rather than the tube or tray format typically associated with the AD8052AR ordering code. The electrical performance of the device is unaffected by the packaging format.
Can the AD8052AR be used to replace two AD8051AR-REEL devices in a design?
Functionally, the AD8052AR provides two amplifiers of the same family as the AD8051AR-REEL in a single package, which can reduce board space. However, the pinout differs from two separate single amplifiers, so the PCB layout and pin assignments must be redesigned and validated against the AD8052 datasheet before substitution.
Are the AD8052AR and AD8051AR-REEL specified over the same temperature range?
Yes. Both devices are rated for the industrial temperature range of −40 °C to +85 °C, as specified in the Analog Devices AD8051/AD8052/AD8054 datasheet.
