Replacement verdict
Compatible functional replacement candidate
The AD8092ARZ and AD8092AR are functionally equivalent dual high-speed operational amplifiers from Analog Devices, sharing identical core electrical specifications, package footprint, and pinout. The AD8092ARZ is the RoHS-compliant lead-free version of the AD8092AR, making it a direct drop-in replacement in most applications, with the primary distinction being environmental compliance rather than electrical performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD8092ARZ | AD8092AR | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op-amps, so the basic amplifier topology and compensation behavior are the same. |
| Number of Channels | 2 | 2 | Both are dual op-amps, so pin count and channel count match for direct substitution. |
| Gain Bandwidth Product | 110 MHz | 110 MHz | Identical bandwidth means AC performance and stability margins are equivalent. |
| Slew Rate | 170 V/µs | 170 V/µs | Same slew rate ensures identical large-signal transient response. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Matching offset voltage means DC accuracy is unchanged when swapping parts. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | Same supply range allows operation in the same circuit rails without redesign. |
| Supply Current per Amplifier | 4.5 mA | 4.5 mA | Identical quiescent current keeps power budget and thermal behavior the same. |
| Input Bias Current | 1.4 µA | 1.4 µA | Same bias current preserves input impedance loading and offset error contributions. |
| Package / Mounting | 8-SOIC (RoHS-compliant) | 8-SOIC (non-RoHS) | Footprint is identical, but the RoHS-compliant Z suffix affects regulatory and solder process compliance. |
| RoHS Compliance | Yes (Pb-free) | No (contains lead) | The Z suffix denotes lead-free/RoHS construction; non-Z parts may not meet current environmental regulations. |

Frequently asked questions
What is the difference between AD8092ARZ and AD8092AR?
The AD8092ARZ is the RoHS-compliant, lead-free (Pb-free) version of the AD8092AR. Both are dual, high-speed, voltage-feedback operational amplifiers from Analog Devices in an 8-lead SOIC package. The "Z" suffix in AD8092ARZ denotes the RoHS-compliant packaging option, while AD8092AR is the non-RoHS (leaded) variant. Electrical performance is identical between the two.
Are AD8092ARZ and AD8092AR electrically and functionally interchangeable?
Yes. Both parts share the same die, pinout, and specified electrical parameters, including a -3 dB bandwidth of 110 MHz (G = +1), slew rate of 170 V/µs, and supply voltage range of 3 V to 12 V. The only documented difference is the RoHS/lead-free status of the package finish, so they are functionally interchangeable in circuit design.
What package do the AD8092ARZ and AD8092AR use?
Both devices are supplied in an 8-lead SOIC (Small Outline Integrated Circuit) package, designated as the "R" package by Analog Devices. The pinout is identical: pin 1 = OUT1, pin 2 = -IN1, pin 3 = +IN1, pin 4 = V-, pin 5 = +IN2, pin 6 = -IN2, pin 7 = OUT2, pin 8 = V+.
Does the AD8092ARZ meet RoHS requirements while the AD8092AR does not?
Yes. The "Z" suffix in AD8092ARZ indicates RoHS compliance with a lead-free (Pb-free) termination finish, per Analog Devices' ordering guide. The AD8092AR is the older non-RoHS version with a leaded finish. Designs requiring RoHS compliance should specify AD8092ARZ.
What are the key AC specifications shared by AD8092ARZ and AD8092AR?
Both parts specify a -3 dB bandwidth of 110 MHz at G = +1, a slew rate of 170 V/µs, and a settling time of 0.1% in 40 ns (typical). These parameters are identical because the two orderable part numbers use the same silicon die; only the package finish differs.
Can AD8092AR be replaced by AD8092ARZ in an existing PCB design?
Yes, in most cases. Because both parts use the same 8-lead SOIC package, pinout, and electrical specifications, AD8092ARZ can be used as a drop-in replacement for AD8092AR. The substitution is recommended when transitioning to RoHS-compliant assemblies; verify solder profile compatibility with the Pb-free finish per the datasheet reflow specifications.
What supply voltage range do AD8092ARZ and AD8092AR support?
Both devices operate from a single supply of 3 V to 12 V or a dual supply of ±1.5 V to ±6 V. They are specified for operation over the industrial temperature range of -40°C to +85°C, making them suitable for a broad range of signal-conditioning and video applications.
