The AD8110 and AD8111 include eight independent output
buffers that can be placed into a high impedance state for paralleling
crosspoint outputs so that off channels do not load the
output bus. The AD8110 has a gain of +1, while the AD8111
offers a gain of +2. They operate on voltage supplies of ±5 V
while consuming only 50 mA of idle current. The channel
switching is performed via a 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.
