GENERAL DESCRIPTION

The AD8186 (G = +1) and AD8187 (G = +2) are high speed, single-supply, triple 2-to-1 multiplexers. They offer –3 dB large signal bandwidth of over 480 MHz along with a slew rate in excess of 1500 V/µs. With better than –80 dB of all hostile crosstalk and –95 dB OFF isolation, they are suited for many high speed applications. The differential gain and differential phase error of 0.05 and 0.05°, along with 0.1 dB flatness to 85 MHz, make the AD8186 and AD8187 ideal for professional and component video multiplexing.
