Daniel, I'm not sure that connecting the negative input to an external 2V reference would help you very much. It depends on the nature of your measurement. I wouldn't be a problem to make the...

SM, After a hard reset, you must write a 0x1 to address 0x15 to get the output clock running. Regards, Jim

Jayant, Rise and Fall times are strongly influence by the pcb, and if we attempt this measurement on our EVM, it probably will not match the values you will see on your board . Our design team has...

Mike, The DAC uses the rising edge of SYSREF so the pulse width will not matter as long as it is not shorter than a multi-frame period (per the standard) if you plan on turning it off. If you leave it...
