ADV3226 750 MHz, 16 × 16 Analog Crosspoint Switch

Product Details

The ADV3226/ADV3227 are high speed 16 × 16 analog crosspoint switch matrices. They offer a −3 dB signal bandwidth greater than 750 MHz and channel switch times of less than 20 ns with 1% settling.

The ADV3226/ADV3227 include 16 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 ADV3226 has a gain of +1 and the ADV3227 has a gain of +2. They both operate on voltage supplies of ±5 V while consuming only 118 mA (ADV3226) and 133 mA (ADV3227) of idle current. 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 ADV3226/ADV3227 are available in the 100-lead LFCSP package over the extended industrial temperature range of −40°C to +85°C.
