The ADV3221 and ADV3222 are high speed, high slew rate, buffered 4:1 analog multiplexers. They offer a -3dB signal bandwidth greater than 800MHz and channel switch times of less than 20ns with 1% settling. With lower than -58dB of crosstalk and -67dB isolation (at 100MHz), the ADV3221 and ADV3222 are useful in many high speed applications. The differential gain error of less than 0.02% and differential phase error of less than 0.02°, together with 0.1dB gain flatness out to 100MHz while driving a 75ohms back terminated load, make the ADV3221 and ADV3222 ideal for all types of signal switching.
The ADV3221/ADV3222 include an output buffer that can be placed into a high impedance state. This allows multiple outputs to be connected together for cascading stages without the off channels loading the output bus. The ADV3221 has a gain of +1, and the ADV3222 has a gain of +2, they both operate on +/-5V supplies while consuming less than 7.5mA of idle current. The channel switching is performed via latched control lines, allowing synchronous updating in a multiple ADV3221/ADV3222 environment.
The ADV3221/ADV3222 are offered in a 16-lead SOIC package and are available over the extended industrial temperature range of -40°C to +85°C.
