The ADV3224/ADV3225 include eight independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs to prevent off channels from loading the output bus. The ADV3224 has a gain of +1 and the ADV3225 has a gain of +2, and they both operate on voltage supplies of ±5 V. Channel switching is performed via a serial digital control that can accommodate the daisy chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array.
