Replacement verdict
Compatible functional replacement candidate
The AD8052ARZ and AD8052AR are functionally equivalent dual high-speed operational amplifiers from Analog Devices, sharing the same core die, package outline, and electrical specifications. The AD8052ARZ is the RoHS-compliant lead-free version of the AD8052AR, making it a suitable drop-in replacement in most applications where lead-free compliance is required or preferred.

Key electrical and mechanical differences between the two devices
| Parameter | AD8052ARZ | AD8052AR | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op-amps, so the feedback topology and compensation behavior are the same. |
| Number of Channels | 2 | 2 | Dual-channel configuration must match for pinout and circuit topology compatibility. |
| Gain Bandwidth Product | 80 MHz | 80 MHz | GBW determines the maximum usable frequency for a given closed-loop gain; identical values ensure equivalent AC performance. |
| Slew Rate | 140 V/µs | 140 V/µs | Slew rate limits large-signal bandwidth; matching values preserve transient response and distortion behavior. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Offset voltage affects DC accuracy; identical limits mean equivalent precision in DC-coupled applications. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | The supply range must cover the application's rails; matching ranges allow direct substitution without rework. |
| Supply Current per Amplifier | 5.5 mA | 5.5 mA | Quiescent current impacts power budget and thermal design; identical values keep power consumption unchanged. |
| Package / Mounting | 8-SOIC (RoHS-compliant) | 8-SOIC | The Z suffix denotes RoHS compliance; both share the same 8-SOIC footprint, so board layout is compatible, but RoHS status differs. |
| RoHS Compliance | RoHS Compliant | Non-RoHS (legacy) | RoHS status affects regulatory compliance and solderability; the non-RoHS version may not be permitted in new designs. |

Frequently asked questions
What is the difference between the AD8052ARZ and the AD8052AR?
The AD8052ARZ and AD8052AR are both dual, low-cost, high-speed voltage-feedback operational amplifiers from Analog Devices. The primary difference is the suffix: the "Z" in AD8052ARZ denotes a RoHS-compliant, lead-free package, while the AD8052AR is the non-RoHS (leaded) version. Both are specified in an 8-lead SOIC package and share the same electrical performance characteristics.
Are the AD8052ARZ and AD8052AR electrically identical?
Yes. Both parts share the same datasheet specifications, including a -3 dB bandwidth of 145 MHz, a slew rate of 170 V/µs, and a supply voltage range of 3 V to 12 V. The only documented difference is the package finish (lead-free vs. leaded), not the silicon or electrical parameters.
Can the AD8052ARZ be used as a direct replacement for the AD8052AR?
Yes, in most cases. Because both devices are pin-compatible 8-lead SOIC parts with identical electrical specifications, the AD8052ARZ can directly replace the AD8052AR. The substitution is recommended when RoHS compliance is required; verify the assembly process is compatible with lead-free (Pb-free) termination finishes.
What is the package and pinout of the AD8052ARZ and AD8052AR?
Both devices are offered in an 8-lead SOIC (Small Outline Integrated Circuit) package. The pinout is identical: pin 1 is OUT1, pin 2 is -IN1, pin 3 is +IN1, pin 4 is V-, pin 5 is +IN2, pin 6 is -IN2, pin 7 is OUT2, and pin 8 is V+. This identical pinout supports drop-in replacement.
What are the key AC specifications of the AD8052ARZ and AD8052AR?
Both parts are specified with a -3 dB bandwidth of 145 MHz (G = +1), a slew rate of 170 V/µs, and a 0.1% settling time of 50 ns. These parameters are identical between the two orderable part numbers because they use the same die and datasheet.
What supply voltage range do the AD8052ARZ and AD8052AR support?
Both devices operate from a single supply of 3 V to 12 V, or from dual supplies of ±1.5 V to ±6 V. This wide supply range makes them suitable for both portable and industrial signal-conditioning applications.
Does the "Z" suffix affect the operating temperature range of the AD8052ARZ?
No. The "Z" suffix indicates RoHS compliance and lead-free construction only. Both the AD8052ARZ and AD8052AR are specified over the industrial temperature range of -40°C to +85°C.
Which part should be selected for a new RoHS-compliant design?
The AD8052ARZ should be selected for new designs requiring RoHS compliance, as it is the lead-free, RoHS-compliant orderable variant. The AD8052AR (leaded) is generally intended for legacy designs or applications where leaded finishes are still permitted.
