DRV134/5 kits anywhere?
Anyone know of anyone selling kits (prefab PCB's, ready to hook) around DRV134/5 balance line drivers?

I googled this up but not in a language I can get...

Digi01 made some nice PCBs awhile back. See Thread

His website can be found here

But take note... he hasn't been online since November 14th.

DRV 134
You dont really need a kit for this one the DRV134 is very easy to use;)

If I had the time to jury rig it, I would not be asking...

Given a PCB layout, it'd make a great group buy...
I've used the DRV134 to drive an input transformer at the other end of the cable. The results are EXCELLENT.

We need a PCB layout thats cheap to fab. I'd recommend sockets
for two DRV134s so a single board can do two stereo channels. I'd
also remove the "option" for 300 ohm resistors and follow the mfg recommendations for an "optional" 10uF tant between signal drive and signal sense.

Further, no regulator onboard is necessary. Leave the regulator
parts choice to the end user who likely is going to have either a
cheapo 7815/7915 scheme, or, a properly implemented LM317/337
scheme or an over-the-top buried zener reference with low noise op-amp servo scheme...

I'd actually like a set: DRV134 and DRV135.

Myself I'd buy 8 sets of each.

Throw in the regulators and I'll get them too...

I am itching for someone to take this on :D

Have not seen the specs but are both 134/135 short protected?

Like this? You can strip off the on-board XLRs if you want to. Board measures 2.3"x1.55".


K-amps 18th December 2006 08:01 PM

LOL Actually I want the sockets in there :-)

Where can we get these?

Nisbeth 18th December 2006 08:05 PM

Heh, I can send you the Eagle files but you'll have to do the rest yourself (including testing if it actually works) [:D]
