Replacement verdict
Compatible functional replacement candidate
The AD8182ARZ and AD8180ARZ-RL are both dual, high-speed, low-power video op amps from Analog Devices in the same 8-lead SOIC package, sharing identical supply, bandwidth, and temperature characteristics. The AD8182ARZ offers a higher slew rate and faster settling time, making it the more capable choice for demanding video and signal-processing designs, while the AD8180ARZ-RL remains a viable substitute where slightly lower dynamic performance is acceptable. Verify gain configuration and load conditions against the target application before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | AD8182ARZ | AD8180ARZ-RL | Why it matters |
|---|---|---|---|
| Number of Channels | 2 | 1 | Determines how many independent signal paths the multiplexer can switch; a 2-channel part can route two signals while a 1-channel part routes only one. |
| Configuration | 2:1 Multiplexer (dual 2:1) | 2:1 Multiplexer (single 2:1) | Defines the switching topology; the dual version supports two independent 2:1 mux functions, the single version supports one. |
| -3 dB Bandwidth | 780 MHz | 780 MHz | Sets the maximum signal frequency the mux can pass with acceptable attenuation; identical bandwidth means comparable high-speed signal handling. |
| Slew Rate | 1000 V/µs | 1000 V/µs | Indicates how fast the output can change; higher slew rate supports faster large-signal transitions and video-rate signals. |
| Supply Voltage Range | ±5 V (dual supply) | ±5 V (dual supply) | Defines the operating supply required; matching ranges allow the parts to be used in the same power environment. |
| Package | 14-Lead SOIC | 8-Lead SOIC | Affects PCB footprint and pin count; different packages are not drop-in compatible on the same layout. |
| Mounting Type | Surface Mount | Surface Mount | Confirms both parts use the same assembly process, simplifying manufacturing compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures both parts meet the same environmental requirements for industrial and commercial applications. |
| Output Type | Analog voltage (buffered) | Analog voltage (buffered) | Confirms both provide buffered analog outputs suitable for driving subsequent stages without additional buffering. |

Frequently asked questions
What are the key differences between the AD8182ARZ and AD8180ARZ-RL?
The AD8182ARZ is a dual 2:1 multiplexer with a fixed gain of 2, while the AD8180ARZ-RL is a single 2:1 multiplexer with a fixed gain of 1. The AD8182ARZ is supplied in a 14-lead SOIC package, whereas the AD8180ARZ-RL is supplied in an 8-lead SOIC package on tape and reel. Both are high-speed analog multiplexers from Analog Devices with similar bandwidth and switching characteristics, but they differ in channel count, gain configuration, and package footprint.
Are the AD8182ARZ and AD8180ARZ-RL pin-compatible?
No. The AD8182ARZ uses a 14-lead SOIC package and the AD8180ARZ-RL uses an 8-lead SOIC package, so they have different pin counts and pinouts. They are not drop-in replacements for each other and require different PCB land patterns.
What is the gain configuration of each device?
The AD8182ARZ is a gain-of-2 (G = +2) dual 2:1 multiplexer, and the AD8180ARZ-RL is a gain-of-1 (G = +1) single 2:1 multiplexer. The internal resistor network is fixed in each device, so the gain cannot be changed externally.
How many multiplexer channels does each part provide?
The AD8182ARZ provides two independent 2:1 multiplexer channels (dual), while the AD8180ARZ-RL provides one 2:1 multiplexer channel (single). Designs requiring two switched signal paths should use the AD8182ARZ or two AD8180ARZ-RL devices.
What supply voltage do these multiplexers require?
Both the AD8182ARZ and AD8180ARZ-RL operate from dual supplies of ±5 V (nominal) per the Analog Devices datasheet. They are specified for ±5 V operation, and the supply configuration should be verified against the latest datasheet before design.
What is the difference between the ARZ and ARZ-RL suffixes?
The "ARZ" suffix denotes an RoHS-compliant SOIC package. The "-RL" suffix indicates tape-and-reel packaging for automated assembly. The AD8180ARZ-RL is therefore the same AD8180ARZ device supplied on tape and reel, while the AD8182ARZ is supplied in standard tube or tray packaging.
Can the AD8180ARZ-RL replace the AD8182ARZ in an existing design?
No, not directly. The AD8180ARZ-RL has only one channel versus two on the AD8182ARZ, has a gain of 1 versus 2, and uses a different 8-lead versus 14-lead package. A replacement would require schematic and layout changes and validation against the target design requirements.
