ADV3220ACPZ-R7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADV3220ACPZ-R7 is a high-speed, buffered 2:1 analog multiplexer manufactured by Analog Devices Inc. It operates on dual ±5 V supplies and features a gain of +2. Key electrical parameters include an 800 MHz −3 dB bandwidth (at 200 mV p-p), a slew rate of 2800 V/μs, and a propagation delay of 650 ps. The device provides low crosstalk of −60 dB at 100 MHz and off-isolation of −88 dB at 5 MHz. It supports switching times of less than 20 ns with 1% settling and includes an output disable function for high-impedance states. The component is housed in an 8-lead LFCSP package and operates within a temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-speed signal routing with excellent video performance metrics including differential gain and phase error below 0.02%.
• Integrated output buffer capable of entering a high-impedance state to prevent loading when cascading multiple devices.
• Optimized for composite video applications where the internal gain of +2 compensates for output termination losses.

Analog Switches, Multiplexers, Demultiplexers Applications

• Routing of high-speed video signals such as NTSC, PAL, S, SECAM, YUV, and RGB.
• Compressed video processing involving MPEG and wavelet formats.
• Telecommunications and data communications systems requiring fast analog switching.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix -R7 corresponds to the 7-inch tape and reel packaging option specified in the manufacturer's ordering guide. Confirm RoHS compliance status via the Z suffix designation. Ensure the selected variant matches the required gain configuration, as the ADV3220 differs from the ADV3219 by its internal +2 gain structure.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a gain of +2 is required for video signal buffering and switching. The ADV3220 is distinct from the ADV3219, which offers unity gain. Designers must account for the specific power supply requirements of ±5 V and ensure proper termination strategies are implemented to maintain the specified bandwidth and flatness characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADV3219/ADV3220 family of high-speed analog multiplexers designed for demanding video and RF applications. While sharing similar pinouts and dynamic performance specifications, the ADV3220 is specifically engineered with an internal resistive feedback network to provide a voltage gain of +2, distinguishing it from the unity-gain ADV3219.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADV3219ACPZ-R7 serves as a functional substitute if the application requires unity gain (+1) rather than the ADV3220's gain of +2. Both components share identical pin configurations, packages, and core switching speeds.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADV3220 differ from the ADV3219?

The primary difference is the internal gain configuration. The ADV3220 provides a gain of +2, whereas the ADV3219 provides a gain of +1. Both share the same package, pinout, and high-speed switching characteristics.

What is the purpose of the EN pin?

The EN (Enable) pin controls the output state. When driven high, it places the output into a high-impedance mode, disconnecting it from the inputs to allow multiple devices to be paralleled without loading the bus.

Why is the exposed pad connected to ground?

For the ADV3220, the exposed pad serves as the ground reference for the internal resistive feedback network. Connecting it to a low-inductance, quiet ground plane minimizes spurious signals and ensures stable gain-of-2 operation.
