GENERAL DESCRIPTION
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.
