AD8180: Single, 2:1 Buffered, 750 MHz, 3.8 mA 10 ns Switching Multiplexer
The AD8180 (single) and AD8182 (dual) are high speed 2-to-1 multiplexers. They offer -3 dB signal bandwidth greater than 780 MHz along with slew rate of 750 V/us. With better than 77 dB of crosstalk and 84 dB of isolation, they are useful in many high speed applications. The differential gain and differential phase error of 0.02% and 0.02°, along with 0.1 dB flatness beyond 100 MHz make AD8180 and AD8182 ideal for professional video multiplexing. They offer 5 ns switching time making them an excellent choice for pixel switching (picture-in-picture) while consuming only less than 3.8 mA (per 2:1 mux) on ±5 V supply voltage.
Both devices offer a high speed disable feature allowing the output to be put into a high impedance state. This allows multiple outputs to be connected together for cascading stages while the "OFF" channels do not load the output bus. They operate on voltage supplies of ±5 V and are offered in 8- and 14-lead PDIP and SOIC packages.
An evaluation board is available for this product and may be ordered using the following product number: AD8180-EB and AD8182-EB. Schematic and layout for this evaluation board is contained in the product datasheet.
