Replacement verdict
Compatible functional replacement candidate
The AD8091AR-REEL7 is a viable functional substitute for the AD8092ARZ in many designs, as both are single-supply, rail-to-rail output voltage-feedback op amps sharing the same SOIC-8 footprint and similar gain-bandwidth characteristics. However, the AD8092ARZ is a dual-channel device while the AD8091AR-REEL7 is a single-channel device, so the replacement is only appropriate where one of the two amplifier channels is unused or where channel count is not a constraint. Supply range, package, and bandwidth align closely, but the channel-count difference and the need to confirm quiescent current and load-driving behavior in the target circuit mean the substitution should be validated before production release.

Key electrical and mechanical differences between the two devices
| Parameter | AD8092ARZ | AD8091AR-REEL7 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (Dual) | 1 (Single) | Channel count determines whether the part can directly replace the other in a circuit; a dual cannot substitute for a single without layout changes. |
| -3 dB Bandwidth | 110 MHz | 110 MHz | Bandwidth defines the maximum signal frequency the amplifier can handle with acceptable gain, critical for high-speed signal chains. |
| Slew Rate | 170 V/µs | 170 V/µs | Slew rate limits how fast the output can respond to large signal swings, affecting distortion and large-signal bandwidth. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | The supply range must match the system rail voltages for the device to operate safely and correctly. |
| Input Offset Voltage (max) | 5 mV | 5 mV | Offset voltage contributes to DC error; matching values ensures comparable accuracy in precision signal paths. |
| Input Bias Current | 1.4 µA | 1.4 µA | Bias current affects DC offset and noise in high-impedance circuits; identical values preserve circuit behavior. |
| Quiescent Supply Current per Amplifier | 4.4 mA | 4.4 mA | Quiescent current impacts power budget and thermal design; matching per-amplifier values keeps power consumption predictable. |
| Package / Pin Count | 8-Lead SOIC | 8-Lead SOIC | Although both use an 8-lead SOIC, the pinout differs between single and dual amplifiers, so footprint compatibility does not guarantee electrical interchangeability. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment to ensure reliable operation and specified performance. |

Frequently asked questions
What are the key differences between the AD8092ARZ and AD8091AR-REEL7?
The AD8092ARZ is a dual, low-cost, high-speed voltage feedback amplifier supplied in an 8-lead SOIC package (RoHS-compliant, tube/tray packaging), while the AD8091AR-REEL7 is a single, low-cost, high-speed voltage feedback amplifier supplied in an 8-lead SOIC package on a 7-inch tape-and-reel. The primary differences are channel count (dual vs. single) and packaging format (tray vs. reel).
Are the AD8092ARZ and AD8091AR-REEL7 pin-compatible?
No. The AD8092ARZ is a dual amplifier with both channels brought out on the 8-lead SOIC, whereas the AD8091AR-REEL7 is a single amplifier in the same 8-lead SOIC footprint but with a different pin function assignment. They share the same package outline but are not pin-for-pin interchangeable.
Can the AD8091AR-REEL7 be used as a drop-in replacement for one channel of the AD8092ARZ?
Not as a direct drop-in. Although both are high-speed voltage feedback amplifiers from the same family, the AD8091AR-REEL7 is a single device with a different pinout than either channel of the AD8092ARZ. A board redesign or pin remapping would be required, and the design should be validated against the respective datasheets.
What are the supply voltage and bandwidth specifications for these amplifiers?
Both the AD8092ARZ and AD8091AR-REEL7 are specified for operation on a single supply of 3 V to 12 V or a dual supply of ±1.5 V to ±6 V. Both offer a −3 dB bandwidth of approximately 300 MHz (G = +1) and a slew rate of about 170 V/µs, per Analog Devices datasheet data.
Why would a designer choose the AD8092ARZ over the AD8091AR-REEL7?
The AD8092ARZ provides two amplifiers in a single 8-lead SOIC package, which saves board space and cost in multi-channel signal chains. The AD8091AR-REEL7 is preferable when only one amplifier channel is needed and tape-and-reel packaging is required for automated high-volume assembly.
What packaging options distinguish the AD8092ARZ from the AD8091AR-REEL7?
The AD8092ARZ is supplied in an 8-lead SOIC in standard tube/tray format and is RoHS-compliant (Z suffix). The AD8091AR-REEL7 is supplied in an 8-lead SOIC on a 7-inch tape-and-reel (REEL7 suffix), which is suited to automated pick-and-place production lines.
Do both parts share the same operating temperature range?
Yes. Both the AD8092ARZ and AD8091AR-REEL7 are specified over the industrial temperature range of −40 °C to +85 °C, per Analog Devices datasheet specifications.
Are the AD8092ARZ and AD8091AR-REEL7 RoHS compliant?
The AD8092ARZ carries the "Z" suffix indicating RoHS compliance. The AD8091AR-REEL7 should be verified against the specific manufacturer datasheet and ordering guide, as RoHS status is tied to the exact orderable part number and revision; designers should confirm compliance from the official Analog Devices product page before finalizing a bill of materials.
