Hi, I would like to know why some DACs have current output instead of voltage output. Is there any advantage with one or the other. Thanks. Amish

The usual situation is that
Current output DACs cn be very fast, gigasamples per second.

Thanks for your answer. I was wonmdering if you could explain the above in more detail or maybe steer me towards a website that has more information on this. Thanks, Amish
Sure!

I was asking more info on the following particular subject: The dac technology (say, cmos switches and thinfilm resistors) isn't suitable for growing good opamps on the same chip. Amish
I'm not an IC designer, so I can't say a lot more. But bipolar processing makes fast, precise opamps, and CMOS makes good switches.
There are some mixed-process dacs with cmos switches and internal opamps, but they tend to be lower, specifically slower, performance parts.
Are there any ic design newsgroups?

I'll do more research. Thanks for your time. Amish
