ADV3219 and ADV3220 are high speed, high slew rate, buffered, 2:1 analog multiplexers. They offer a -3dB signal bandwidth greater than 800MHz and channel switch times of less than 20ns with 1% settling. With -60dB of crosstalk and -82dB isolation (at 100MHz), the ADV3219 and ADV3220 are useful in many high speed applications. The differential gain of less than 0.02% and the differential phase of less than 0.02°, together with 0.1dB flatness beyond 100MHz while driving a 75ohms back terminated load, make the ADV3219 and ADV3220 ideal for all types of signal switching.
ADV3219/ADV3220 include an output buffer that can be placed into a high impedance state to allow multiple outputs to be connected together for cascading stages without the off channels loading the output bus. The ADV3219 has a gain of +1, and the ADV3220 has a gain of +2, they both operate on +/-5 V supplies while consuming less than 7.5mA of idle current.
The ADV3219/ADV3220 are available in the 8-lead LFCSP package over the extended industrial temperature range of -40°C to +85°C.
