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 isolation (@ 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, 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 reprogramming the entire array.

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.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
