ADI ADV3219ACPZ

The ADV3219 and ADV3220 are high speed, high slew rate, buffered, 2:1 analog multiplexers. They offer a −3 dB signal bandwidth greater than 800 MHz and channel switch times of less than 20 ns with 1% settling. With −82 dB of crosstalk and −88 dB isolation (at 5 MHz), 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 0.1 dB flatness beyond 100 MHz while driving a 75 Ω back terminated load, make the ADV3219 and ADV3220 ideal for all types of signal switching. The 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 7.5 mA 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.
