DAC recommendations

Post by YahooArchive »

I just determined that I need a DAC for my application. Can I get a
recommendation of a DAC that will integrate with the Pro board easily?

I also need to sink 0 < 1 Amp of current in a Digital-to-current operation. I
don't think that's an off-the-shelf part.

The SuperPRO has a 10 bit DAC on one of the AD pins.

Other than that I like the MicroChip MCP47x6 which is available in different #
of bits, and is quite small, easy to use...

As for sinking 1A are you saying a controlled current source/sink for that or
just a switch like a big MOSFET.

Yes. it must be a controlled current. I'm sure 8-10 bits is sufficient
resolution.
