Hi,
I have been looking for some current source DAC, and have found a few types but I am having issue reading the datasheet.
Some of them give the output min and mac I that the DAC can provide, which makes sense to me but other give input capacitance and "some type" of voltage.
Can you have a look at this datasheet please:
http://www.analog.com/static/imported-files/data_sheets/AD5428_5440_5447.pdf
the specs for output are on the 3 page.
First question would be: Why do I need the input capacitance when I am interested for the output current.
How can I find this current when I am given only voltage and the chip is said to be a current source?
Are there any multiple channel DAC with 0 mA to several mA available on the market?
Thank you in advance
