ADC board

[carlmart]

There are many DAC topics on this forum, but I couldn't find any on ADC.

Neither could I find any boards googling around, except for evaluation boards.

What I would need is something complete, with USB output and all.

Has anyone assembled something like that or has information on any?

There are some threads about digitizing vinyl and there's this thread

Very basic DSD ADC made with op-amps and logic gates

but I never finished the software needed for using the USB interface.

There's this PCM 1808 ADC board available from lots of sellers PCM1802 Audio Stereo A/D Converter ADC Decoder 24bit 96kHz Amplifier Player Board ANALOG INPUT Module-in Replacement Parts & Accessories from Consumer Electronics on Aliexpress.com | Alibaba Group

You could potentially interface that with a miniDSP ministreamer or similar i2s - USB device.

Yeah, I saw some cheap PCM1808 boards on eBay. But it doesn't seem much to go on.

Complete ADC boards, with analog going in and usb going out there are not.

I'm just checking to see if that's so.

My main application for A/D now is digitizing my LP collection.

I already have a Behringer UCA202, which is very popular and sounds reasonably well. But it's only 16 bit 48KHz, and I wonder if a higher A/D resolution wouldn't sound better.

I also have a Tascam DR70 recorder, which it is high resolution, but I would like to find an external, line level, A/D box.

Evaluation A/D boards are an option, but none seem to have USB interface.

Try to find an old EMU0404, its ADC is from AKM and measures great !

Add this. ministreamer. Limited to 96K.

I had a look at people who bought the EMU in Amazon, and there's lot of people who didn't like it or had problems with it. Low approval rate: more than 30% bombed it.

It's not cheap in my country either.

Perhaps something better from Behringer?

My concern is the input preamps, as most AD units I see have mic preamps which I do not need.

Perhaps something like the BEHRINGER U-PHORIA UMC204HD might do? It's 24-Bit/192 kHz. I don't know how good are those Midas preamps they use.

Just picked the Behringer as an example.

Where are the L/R analog inputs?

Add it to an evaluation board with digital O/P.

 

[carlmart]

What I need to have is an USB output to go into a laptop.

Would that ministreamer provide that?

Sorry, I am not familiar with streamers.

 

[rfbrw]

Yes. It will provide USB I/O for your laptop.

Now I need an ADC evaluation board recommendation.

Would these two boards cost less than a BEHRINGER U-PHORIA UMC204HD ($99)?

Add the cost of the board that I linked to on Aliexpress to the cost of the ministreamer board.

The Behringer might be more suitable if you don't want to DIY the two units together.
