Replacement verdict
Compatible functional replacement candidate
The AD8058ARZ is a viable functional replacement candidate for the AD8052ARZ in many dual-supply signal-chain designs, since both are dual high-speed voltage-feedback op amps in the same 8-lead SOIC package with comparable bandwidth and supply range. However, the AD8058ARZ draws notably higher quiescent current per amplifier and offers a different output drive and noise profile, so the replacement should be validated against the target application's power budget, load drive, and noise requirements before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | AD8052ARZ | AD8058ARZ | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count is compatible for dual-channel signal chains. |
| -3 dB Bandwidth | 110 MHz | 325 MHz | Higher bandwidth affects achievable signal frequency and settling behavior in high-speed applications. |
| Slew Rate | 170 V/µs | 1000 V/µs | Slew rate limits large-signal response speed and distortion at high frequencies. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | Compatible supply range allows drop-in use in the same power rail design. |
| Input Offset Voltage (max) | 5 mV | 6 mV | Offset voltage impacts DC accuracy; similar values mean comparable precision in DC-coupled stages. |
| Input Bias Current | 1.4 µA | 1.5 µA | Bias current affects error in high-impedance feedback networks; close values ease substitution. |
| Quiescent Supply Current | 5.5 mA | 11 mA | Power budget differs significantly; the higher current part may require thermal and supply reconsideration. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Identical package and pinout enable direct board-level replacement. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +85 °C | The narrower temperature range of the second part may limit use in harsh environments. |

Frequently asked questions
What are the primary differences between the AD8052ARZ and AD8058ARZ?
The AD8052ARZ is a dual, voltage-feedback operational amplifier, while the AD8058ARZ is a dual, current-feedback operational amplifier. Both are offered in an 8-lead SOIC package, but they differ in feedback architecture, bandwidth, slew rate, and input bias current characteristics, making them suited to different signal-chain requirements.
How do the bandwidth specifications of the AD8052ARZ and AD8058ARZ compare?
The AD8052ARZ provides a -3 dB bandwidth of approximately 110 MHz at a gain of +1, whereas the AD8058ARZ provides a -3 dB bandwidth of approximately 325 MHz at a gain of +1. The current-feedback architecture of the AD8058ARZ supports higher bandwidth, particularly at higher gains.
How do the slew rates of the AD8052ARZ and AD8058ARZ differ?
The AD8052ARZ has a slew rate of approximately 145 V/µs, while the AD8058ARZ has a slew rate of approximately 1000 V/µs. The significantly higher slew rate of the AD8058ARZ makes it preferable for high-speed pulse and large-signal applications.
Are the AD8052ARZ and AD8058ARZ pin-compatible in the SOIC-8 package?
Both devices are offered in an 8-lead SOIC package with the same standard dual op-amp pinout (two inputs, two outputs, and supply pins). However, pin compatibility does not guarantee functional interchangeability because the feedback architectures differ, so circuit performance must be revalidated before substitution.
Which device is better suited for high-gain applications?
The AD8058ARZ, being a current-feedback amplifier, maintains its bandwidth relatively independent of closed-loop gain, making it better suited for high-gain configurations. The AD8052ARZ, as a voltage-feedback amplifier, exhibits gain-dependent bandwidth rolloff and is typically used where its voltage-feedback behavior is preferred.
How do the input bias currents of the AD8052ARZ and AD8058ARZ compare?
The AD8052ARZ has an input bias current of approximately 1.4 µA per input, while the AD8058ARZ has an input bias current of approximately 5 µA per input. Designs with high source impedance should account for the larger bias current of the AD8058ARZ when evaluating offset errors.
What supply voltage ranges do the AD8052ARZ and AD8058ARZ support?
Both the AD8052ARZ and AD8058ARZ operate from dual supplies of ±5 V or single supplies of +5 V to +12 V, with a specified supply range of 4.5 V to 12 V. Designers should confirm the exact operating conditions against the respective manufacturer datasheets.
Can the AD8052ARZ and AD8058ARZ be used interchangeably in an existing design?
They should not be treated as drop-in replacements. Although both are dual op-amps in an 8-lead SOIC package, the voltage-feedback AD8052ARZ and current-feedback AD8058ARZ require different external component selection and stability considerations, so any substitution must be validated against the manufacturer datasheets and the target circuit.
