while the AD8105 has a differential gain of +2 for ease of use

in back-terminated load applications. They operate as fully

differential devices or can be configured for single-ended

operation. Either a single +5 V supply or dual 2.5 V supplies

can be used, while consuming only 340 mA of idle current with

all outputs enabled. The channel switching is performed via a

double-buffered, serial digital control (which can accommodate

daisy-chaining of several devices), or via a parallel control,

allowing updating of an individual output without reprogram-

ming the entire array.

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 (@ 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.

The AD8104/AD8105 include 16 independent output buffers

that can be placed into a high impedance state for paralleling

crosspoint outputs so that off-channels present minimal loading

to an output bus. The AD8104 has a differential gain of +1,

The AD8104/AD8105 are packaged in a 304-ball BGA package

and are available over the extended industrial temperature

range of −40°C to +85°C.
