Digital to Analog converter DAC

Hi,

I'm working with a DSP, but I need a DAC with this characteristics:

-16 bits resolution
-sample frecuency = between 100 Khz and 250KHz, because I'm working
with a signal between DC and 50KHz.
Optional: an interface SSI to communicate with a DSP, but is absolutely
necessary 16 pins to pass the data in a parallel way.

Do you know a DAC  with this features.
Thak you

There are lots of them.  I'd start with TI (they have the old Burr-Brown 
stuff), Analog Devices, Linear Technologies and Maxim.  Maxim makes good 
parts, but they have strange and often frustrating stocking and ordering 
policies -- I would only use them for jelly-bean parts or if I 
absolutely positively needed something that only they had.  I wouldn't 
stop there -- DAC's are a popular part, most everyone makes them and 
16-bit, 100ksps parallel load DAC's are not oddball in any way shape or 
form.

Thank you Tim.

Maybe you cold send me some DAC's numbers and the company that biult
it, the features and the posible problems, I need to do a FFT.

Than you again.

Or, here's a crazy thought...  You could perhaps make an effort
yourself, be grateful for the help you already got, and do your
job, instead of asking others to do it for you.

Yes, yes I know I'm going to get flamed for this...  But, frankly,
what you're asking seems excessive/abusive to me.  It's not like
people in this newsgroup are being paid to do other people's jobs!

That's work, and I'll do it for my regular rate.  Contact me (my contact 
info's on my website) and we can work out the details of what 
requirements you need to fill and how much I'll get paid.

Otherwise, look on the websites of the manufacturers that I mentioned, 
and look for manufacturer's that I didn't mention so you can look on 
their websites, too.  Map your requirements into their specifications 
and see which one is the best for you.

The fact that you're doing an FFT is totally immaterial to your DAC 
choice, as FFT's are done in processors and DAC's turn digital data into 
analog voltages.

Excuseme Tim. This message is for Carlos


Please Carlos...
If you don't like help me, entonces CALLATE... Y NO MOLESTES... por tu

Hi. I'm from Ecuador. Why you question it?
