Replacement verdict
Compatible functional replacement candidate
The AD8182ARZ and AD8180ARZ are functionally comparable analog multiplexers sharing the same package, supply requirements, and switching architecture, making the AD8182ARZ a viable replacement candidate for the AD8180ARZ in most designs. The primary distinction is the channel configuration, so engineers should confirm that the 2:1 differential topology of the AD8182ARZ satisfies the intended signal-routing requirements before substituting it in existing layouts.

Key electrical and mechanical differences between the two devices
| Parameter | AD8182ARZ | AD8180ARZ | Why it matters |
|---|---|---|---|
| Number of Channels | 2 | 1 | Determines how many independent signal paths can be switched; a 2-channel part can replace a single-channel part only if the extra channel is unused or tied off. |
| Configuration | 2:1 Multiplexer (dual SPDT) | 2:1 Multiplexer (single SPDT) | Defines the switching topology; both are 2:1 muxes but the dual version integrates two independent switches in one package. |
| -3 dB Bandwidth | 780 MHz | 780 MHz | Sets the maximum signal frequency the switch can pass with acceptable attenuation; matching bandwidth means comparable high-speed signal fidelity. |
| Slew Rate | 1000 V/µs | 1000 V/µs | Governs how fast the output can track large signal transitions; identical slew rate supports equivalent transient performance. |
| Supply Voltage Range | ±5 V (dual supply) | ±5 V (dual supply) | Must match the system power rails; identical supply requirements allow drop-in use in the same circuit. |
| Package | 14-Lead SOIC | 8-Lead SOIC | Footprint and pin count differ, so board layout and pinout compatibility must be verified before substitution. |
| On Resistance | Low (typ. ~10 Ω) | Low (typ. ~10 Ω) | Affects signal attenuation and loading; similar on-resistance yields comparable insertion loss. |
| Channel-to-Channel Crosstalk | Low (high isolation) | Low (high isolation) | Determines signal leakage between channels; good isolation preserves signal integrity in multiplexed systems. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms both parts are rated for the same industrial temperature environments. |

Frequently asked questions
What are the key differences between the AD8182ARZ and AD8180ARZ?
The AD8182ARZ is a dual 2:1 multiplexer, while the AD8180ARZ is a single 2:1 multiplexer. Both are high-speed, low-power analog multiplexers from Analog Devices in 8-lead SOIC packages, but the AD8182ARZ integrates two independent multiplexer channels in one package, whereas the AD8180ARZ provides one channel.
Are the AD8182ARZ and AD8180ARZ pin-compatible?
No. The AD8182ARZ is an 8-lead SOIC device containing two multiplexer channels, and the AD8180ARZ is an 8-lead SOIC device containing one multiplexer channel. Because the internal channel count differs, the pin functions and signal assignments are not identical, so they should not be treated as drop-in replacements without verifying the pinout against the respective datasheets.
What is the typical -3 dB bandwidth of these multiplexers?
Both the AD8180ARZ and AD8182ARZ are specified with a typical -3 dB bandwidth of 750 MHz, making them suitable for high-speed video and signal-routing applications.
What supply voltage do the AD8182ARZ and AD8180ARZ require?
Both devices operate from a dual supply of ±5 V (nominally ±4.5 V to ±5.5 V), consistent with the Analog Devices AD8180/AD8182 datasheet specifications.
How much power do the AD8182ARZ and AD8180ARZ consume?
The AD8180ARZ (single channel) typically dissipates about 25 mW, while the AD8182ARZ (dual channel) typically dissipates about 50 mW, reflecting the additional multiplexer channel in the dual version.
What is the switching time of the AD8182ARZ and AD8180ARZ?
Both devices feature fast switching with a typical channel switching time of approximately 4 ns, enabling rapid signal routing in high-speed systems.
Can the AD8182ARZ be used to replace two AD8180ARZ devices?
Functionally, the AD8182ARZ provides two independent 2:1 multiplexer channels in a single 8-lead SOIC package, which can replace two AD8180ARZ channels in terms of channel count. However, the pinout and PCB layout differ, so the board must be redesigned and the shared control and supply pins verified against the AD8182ARZ datasheet before substitution.
What are the typical applications for the AD8182ARZ and AD8180ARZ?
Both multiplexers are intended for high-speed signal routing such as video switching, RGB routing, HDTV signal selection, and other broadband analog multiplexing applications where low power and fast switching are required.
