AD8185 310 MHz, 25 mA, Triple 2:1, Buffered (Gain = +2) Multiplexer

The AD8183 (G = +1) and AD8185 (G = +2) are high speed Triple 2-to-1 multiplexers. They offer -3 dB full signal bandwidth up to 360 MHz along with slew rate in excess of 1000 V/µs. With better than -72 dB of all hostile crosstalk and 100 dB of isolation, they are useful in many high speed applications. The differential gain and differential phase error of 0.01% and 0.02°, along with 0.1 dB flatness to 90 MHz make AD8183 and AD8185 ideal for professional video and LCD multiplexing. They offer 15 ns switching time making them an excellent choice for switching video signals, while consuming less than 25 mA on ±5 V supply voltage.
