Hi Team,

I'm planning to use the DAC IC DAC80502 or DAC80504 for my application. In the specification or datasheet i didn't find the sample rate of the DAC IC.

What is the sampling rate of above mentioned DACs per channel?

Regards,

Abhishek

Hi Team,

My required speed is 34MSPS per DAC channel.

Hi,

The DAC must be an SPI DAC.

Hi Abhishek,

I moved your thread from yesterday to the high-speed DAC team. I believe they are looking into it now. The part you linked yesterday as well as today are all precision DACs. We don't have any precision DACs that'll reach 34MSPS. Max SPI frequency in our precision DACs is 50MHz and it takes multiple SPI clocks to get one DAC update. There is no way to achieve 34MSPS.

Check the high speed portfolio here: High-speed DACs (>10 MSPS) product selection | TI.com

Or wait for their response in your other thread.

Best,

Hi Abhishek, the closet DAC we have is DAC2932 (12b, 2ch, 40MSPS) or THS5671A (14b, 1ch, 125MSPS) and both use a Parallel CMOS interface for the input data.
