Re: Very Late Start - Type 2
I bought this:toggle quoted messageShow quoted text
but I recommend you spend $20 more and get one with transformers
or at least with video op-amps. The DACs in the AD9959 steer a
constant current through differential outputs, and it's important that
these outputs see the exact same load impedances to keep the
currents in balance. If not, the steered current fluctuates and that
makes the channels interfere with each other somewhat.
The bare chip is available (end of reel surplus) for ten bucks on
Aliexpress, if you can deal with the SMD.
Second-hand gear is very expensive here in Australia. It's a small
enough market that it all gets bought by dealers who are prepared
to price it high and wait a long time.
