ADV3221ARZ Übersicht
An analog multiplexer is a switching IC that connects one of several input terminals to a common output path. A 4:1 device such as the ADV3221 belongs to the broader analog switch and multiplexor hierarchy, where input isolation, signal integrity, bandwidth, and control timing determine whether it can preserve a waveform during channel changes. Unlike an unbuffered passive switch, the ADV3221 includes active output drive to maintain a controlled signal path at high frequencies.
Key features include 2400 V/µs slew rate, low 75 mW power consumption from ±5 V supplies, and strong video performance, including 100 MHz operation with 0.1 dB video bandwidth variation according to the supplied datasheet excerpts. The manufacturer describes the ADV3221 as a high-speed, high-slew-rate buffered 4:1 analog multiplexer, making it appropriate for video routing, instrumentation, test systems, and other wideband signal paths.
The ADV3221 and closely related ADV3222 family uses double-buffered logic, allowing a new selection to be prepared before the switching interval. This architecture supports controlled break-before-make transitions and makes timing easier to coordinate in multi-channel systems. Signal amplitude can influence the quoted bandwidth, so system designers should compare performance at their actual operating amplitude rather than relying only on the headline 800 MHz figure.
Typical applications include video test and measurement equipment, high-speed data-acquisition front ends, broadcast and professional video routing, and wideband communication test paths. The 16-SOIC footprint is suitable for conventional surface-mount assembly, although high-speed layouts must minimize trace lengths and provide a controlled return path.
The primary design considerations are supply decoupling, controlled-impedance routing, grounding, and careful interpretation of the input and output common-mode limits. Because the manufacturer excerpt describes performance at ±5 V, engineers should verify the complete electrical limits and dual-supply requirements in the official datasheet before committing to a system design.
This page consolidates verified manufacturer and distributor information, source-backed application guidance, parameter comparisons, and practical implementation notes. It adds engineering context around bandwidth, switching behavior, packaging, and sourcing while clearly separating verified specifications from parameters that still require direct datasheet confirmation.

Typische Anwendungen
ADV3221ARZ ist geeignet für 6 Anwendungs: High-Speed Video Routing, Video Test and Measurement, Broadband Communication Test, High-Speed Data Acquisition Front End, Professional Video Signal Switching, Industrial Instrumentation Signal Multiplexing.
High-Speed Video Routing
The ADV3221ARZ fits wideband video selection because its verified performance includes an 800 MHz −3 dB bandwidth at 200 mV p-p, 750 MHz at 2 V p-p, 2400 V/µs slew rate, and 0.1 dB video bandwidth variation at 100 MHz. Place the device between four source paths and a downstream receiver, then use the double-buffered logic to prepare a new channel selection. Controlled-impedance routing and short traces are essential because the quoted large-signal bandwidth is lower than the small-signal value.
Empfohlen
Video Test and Measurement
The ADV3221ARZ is suitable for selecting among four video or composite test sources when rapid channel changes and high-frequency transparency are required. Its less-than-20 ns switching to 1% settling allows short acquisition intervals, while the 750 MHz bandwidth at 2 V p-p covers more practical signal amplitudes than the 800 MHz small-signal figure alone. Buffer the selected output as needed and verify return loss and channel-to-channel timing in the final fixture.
Empfohlen
Broadband Communication Test
The ADV3221ARZ can route four high-frequency analog paths in communication test equipment without relying on a slow discrete switch matrix. Its 800 MHz small-signal bandwidth, high slew rate, and buffered topology support controlled signal delivery to downstream analysis circuitry. Keep source and load impedances consistent with the manufacturer test conditions, because those impedances influence insertion loss, bandwidth, and the usable settling response.
Empfohlen
High-Speed Data Acquisition Front End
The ADV3221ARZ can select among four synchronized analog inputs in a wideband data-acquisition front end. The four-to-one topology reduces the number of separate high-speed paths, while the 2400 V/µs slew rate and broad bandwidth help preserve transitions when the source impedance is appropriate. Designers should account for channel-to-channel delay, crosstalk below 58 dB, and the less-than-20 ns settling specification when configuring acquisition windows.
Empfohlen
Professional Video Signal Switching
The ADV3221ARZ suits professional video routing where four sources must be selected without sacrificing amplitude or high-frequency content. Its 0.1 dB bandwidth variation at 100 MHz provides a concrete amplitude-flatness reference, while the buffered output helps isolate the selected path from source loading. For 75-ohm video systems, preserve the intended characteristic impedance and validate return loss on the selected PCB stack-up rather than assuming the bare IC specification applies directly.
Empfohlen
Industrial Instrumentation Signal Multiplexing
The ADV3221ARZ is applicable when an industrial instrument must select among four wideband sensor or excitation paths. Its buffered 4:1 topology reduces routing complexity, while the verified 800 MHz bandwidth and less-than-20 ns switching support fast-changing test sequences. Industrial input signals still require protection, scaling, and grounding appropriate to the source; the IC should not be treated as a surge-protection device or a substitute for front-end signal conditioning.

Wichtigste Unterscheidungsmerkmale
- Wideband buffered multiplexing (vs. ADV3222ARZ)
- Fast channel transitions (vs. ADV3222ARZ)
- Large-signal performance disclosed separately (vs. ADV3222ARZ)
- Explicit video flatness metric (vs. ADV3222ARZ)
Designhinweise
Route the selected high-frequency path as a controlled-impedance trace and keep the mux, source, and load electrically close. A discontinuity between a 750–800 MHz capable device and an ordinary PCB trace can dominate insertion loss and return loss. Use a continuous reference plane, avoid stubs and test pads, place decoupling capacitors close to the supply pins, and preserve the manufacturer’s recommended ground-return geometry.
Evaluate bandwidth at the actual signal amplitude. The verified datasheet excerpts specify 800 MHz at 200 mV p-p but 750 MHz at 2 V p-p, showing amplitude-dependent performance. Include the source impedance, load impedance, cable or connector, and receiver input capacitance in simulation or bench validation. If timing depends on channel transitions, include the specified less-than-20 ns settling to 1% criterion rather than relying on rise time alone.
Provide low-impedance ±5 V rails while observing the verified ±4.5 V to ±5.5 V supply range. Place the required bypass capacitors at the device pins with short ground returns, and keep analog and digital return currents from sharing long paths where they can couple into the selected channel. The quoted 75 mW consumption applies at ±5 V, but total board dissipation and nearby heat sources still require normal power-supply and thermal-budget checks.
Do not select a replacement by channel count alone. ADV3221ARZ combines a specific 16-lead SOIC pinout, double-buffered control logic, dual-supply operation, 800 MHz-class bandwidth, and less-than-20 ns settling. A generic 4:1 mux may reverse address logic, change enable polarity, use a different supply arrangement, or introduce unacceptable capacitance. Verify every pin and AC parameter against the official data sheet before approving a substitution.
