There isn't an eval board for the AD5641 - what's the best EVB choice for evaluating this part?

Hi,

I have a new design with an AD5641 with a 5V VDD supply. At the risk of humiliating myself with full scale code loaded (0x3FFF) the output voltage is 2.5V and i'm expecting 5V. Can someone shed some light on what is going on. 

Thanks,

Richard

Hey everyone I have a problem communicating with a AD5641 DAC. I am making this project with Arduino UNO and I can't seem to figure out how to properly send data to the DAC. If someone can give me an example or explain how to send data to this DAC I'd…

where can I find the IBIS Model of  AD5160 and AD5641?

Hi all!

I have an AD5641 running at 5V supply, controlled by a 3.3V SPI line at 20MHz clock rate. (30 MHz are allowed according to datasheet). A sum of a small 100kHz sine wave ( 20 to 40mV Vpp) and a DC offset has to be generated. A bigger signal at…

What can I expect if the AD5641 output is shorted to ground?

The datasheet shows a short circuit current of 15mA but no other references to this type of fault. 

It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.

In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…

For low power application that requires RRIO and greater than 5V supply, I would recommend the AD8657 due to its low supply current of 22 uA per amplifier. The AD8657 is a 18V, micropower, rail-to-rail RRIO amplifier optimized for low power and wide operating…
