Replacement verdict
Compatible functional replacement candidate
The AD8052ARZ and AD8054AR are both high-speed voltage-feedback operational amplifiers from the same Analog Devices AD805x family, sharing identical supply voltage ranges, bandwidth class, and SOIC package style. The primary distinction is channel count: the AD8052ARZ is a dual-channel device while the AD8054AR is a quad-channel device. For designs where board space and channel count permit substitution, the AD8054AR can serve as a functional replacement candidate, but the difference in channel count and package footprint must be validated against the target application before committing to a drop-in replacement.

Key electrical and mechanical differences between the two devices
| Parameter | AD8052ARZ | AD8054AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 4 | Determines how many independent signal channels can be processed in one package; a dual vs quad affects board layout and channel count. |
| Gain Bandwidth Product | 80 MHz | 80 MHz | Sets the maximum frequency at which the amplifier can provide useful gain; matching values means similar high-frequency capability. |
| Slew Rate | 140 V/µs | 140 V/µs | Governs how fast the output can respond to large signal changes; identical slew rates indicate comparable large-signal dynamic performance. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | Defines the allowable power supply window; matching ranges allow the same supply rail design for both parts. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Affects DC accuracy; equal offset specs mean similar precision in DC-coupled applications. |
| Input Bias Current | 1.4 µA | 1.4 µA | Influences error in high-impedance circuits; identical bias currents give comparable input loading behavior. |
| Quiescent Supply Current per Amplifier | 5.5 mA | 5.5 mA | Determines power consumption; per-amplifier current is similar, but total package current scales with the number of amplifiers. |
| Package Type | 8-Lead SOIC | 14-Lead SOIC | Footprint and pin count differ, so the PCB layout must be redesigned when substituting one for the other. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Confirms both parts are rated for the same environmental conditions, supporting use in similar industrial applications. |

Frequently asked questions
What are the key differences between the AD8052ARZ and AD8054AR?
The AD8052ARZ is a dual, voltage-feedback operational amplifier supplied in an 8-lead SOIC package, while the AD8054AR is a quad, voltage-feedback operational amplifier supplied in a 14-lead SOIC package. Both are fabricated on the same high-speed complementary bipolar process and share similar per-amplifier AC and DC performance, but they differ in channel count, package pinout, and total quiescent current.
Are the AD8052ARZ and AD8054AR pin-compatible?
No. The AD8052ARZ uses an 8-lead SOIC (R-8) package with two amplifiers, and the AD8054AR uses a 14-lead SOIC (R-14) package with four amplifiers. The pin counts, pin assignments, and PCB land patterns differ, so they are not drop-in replacements for one another.
Do the AD8052ARZ and AD8054AR have the same bandwidth and slew rate specifications?
Yes, per-amplifier AC specifications are essentially the same. Both devices are specified with a -3 dB bandwidth of 145 MHz (G = +1) and a slew rate of 170 V/µs, reflecting their common high-speed complementary bipolar process and voltage-feedback architecture.
How does the supply current compare between the AD8052ARZ and AD8054AR?
The AD8052ARZ (dual) is specified with a total supply current of approximately 5.5 mA typical at ±5 V, while the AD8054AR (quad) is specified with a total supply current of approximately 11 mA typical at ±5 V. The quad device draws roughly twice the total quiescent current because it contains twice as many amplifiers, with similar per-amplifier current.
What are the input voltage range and output swing characteristics of these amplifiers?
Both the AD8052ARZ and AD8054AR are specified for operation on dual supplies of ±5 V (or single supply of 5 V to 12 V) with an input common-mode voltage range that extends from approximately -4.0 V to +4.0 V on ±5 V supplies. Their rail-to-rail output stage swings to within approximately 1 V of each supply rail under rated load conditions.
Can the AD8052ARZ and AD8054AR be used in single-supply applications?
Yes. Both devices are specified for single-supply operation over a range of 5 V to 12 V, in addition to dual-supply operation of ±2.5 V to ±6 V. Their input common-mode range and output swing support single-supply signal chains, provided the input and output headroom limits are respected in the design.
Which device should be selected for a design requiring four high-speed amplifiers in the smallest board area?
The AD8054AR is the appropriate choice when four amplifiers are required, since it integrates four channels in a single 14-lead SOIC package and avoids the board area and component count of two AD8052ARZ dual packages. If only two channels are needed, the AD8052ARZ provides the same per-amplifier performance in a smaller 8-lead SOIC package.
