ADI ADV3229ACPZ

The ADV3228/ADV3229 are high speed 8×8 analog crosspoint switch matrices. They offer a -3 dB large signal bandwidth of 750 MHz (ADV3228) and a slew rate of 2500 V/μs. The ADV3228/ADV3229 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 ADV3228 has a gain of +1, the ADV3229 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 daisy chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array. The ADV3228/ADV3229 are available in the 72 - lead LFCSP package over the extended industrial temperature range of -40°C to +85°C.
