AD8105ABPZ

GENERAL DESCRIPTION

The AD8104/AD8105 are high speed, 32 × 16 analog crosspoint switch matrices. They offer 600 MHz bandwidth and slew rate of 1800 V/µs for high resolution computer graphics (RGB) signal switching. With less than −70 dB of crosstalk and −90 dB isola tion (at 5 MHz), the AD8104/AD8105 are useful in many high speed applications. The 0.1 dB flatness, which is greater than 50 MHz, makes the AD8104/AD8105 ideal for composite video switching.
