Looking for DAC chip with >=1M sample rate

Hi,

what kind of application? Is it for arbitrary waveform generation? Dual Channel necessary?

Resolution requirements?

Have a look at DAC8822 which is 16bit, dual channel MDAC.

How about DAC11001a? Is it new compared to 8822?

In fact, I need 2 voltage sources. But I think I can use 2 11001A.

If I want to use Arduino to control it in prototyping phrase, can you provide tech support?

DAC8822 main page says its output is Unbuffered Current, what's the diff from Unbuffered Voltage?

Today I received 11001EVM board.

By following its user guide, I am able to update firmware in MSP432E401Y board. However, after I connected MSP with EVM board, and plugged USB to u7 port, the 2  ACCtrl serial ports still not appear in my computer, same issue with 81404EVM. Last time I suspect my 81404EVM is damaged. Now it seems some part of MSP432 is spoiled.

Another issue: I don't see the white dot besides many jumpers to indicate pin 1. For example, jumper 7 is showed in the following pictures. Where is the dot?

In table 5 of jumper settings, for most of them I don't see dot on the hardware board, so very hard for me to verify.

I don't think it's due to admin right.

The MSP side USB is OK, I could use UniFlash to detect and update firmware. It's the U7 port part.

Now I am more interested in using Arduino to communicate and control two EVM boards. Are you working on that? If so, please provide me wiring details for 81404 first.

Hi,

We are not working with Arduino. Anbu will send the debug details for MSP.

Also please dont mix up the thread. Each thread is used for single device, so that we can support you better. Please use this thread for DAC11001EVM and the other thread we will discuss about DAC81404EVM

Hi ,

1. Please find the jumper pin no highlited in blue mark. hope it will help.

2.  i am not faced this kind of communication error in my laptop sofar. could you try with different USB port in laptop or another laptop ?

3. We are not familiar with Arduino hardware, but you can easy to communicated with DAC if you meet SPI timing  as mentioned in data sheets with any SPI master.
