Description

The AD8180 (single) and AD8182 (dual) are high speed 2-to-1 multiplexers. They offer 3 dB signal bandwidth greater than 750 MHz along with slew rate of 750 V/ms. With better than 80 dB of crosstalk and 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 the AD8180 and AD8182 ideal for professional
video multiplexing. They offer 10 ns switching time making them an excellent choice for pixel switching (picture-in-picture) while consuming less than 3.8 mA (per 2:1 mux) on ±5 V supply voltages.

Both devices AD8180 (single) and AD8182 (dual) offer a high speed disable feature allowing the output to be configured 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 plastic DIP and SOIC packages.
