Has anyone developed any applications or VIs for an AD7731 from Analog devices?

[gmarz5]

I am trying to develop an interface to an AD7731. I am using a PCI-6543 in burst mode but having problems with writing, reading and timing. I can get some data from the IC but not continuously.

Hi,

after having a look to Datasheet of AD7731 it seems to me, that you will go into trouble if you use burst mode. Try first to get single output values in loop with enough delay in this loop. Then decrease delay time -- you will see, when first errors appear.

By the way - for this kind of "slow" ADC's is the Printerport fast enough. Find attached a pict. of Frontpanel, how I have tested
a 16Bit DAC (AD660) and 16 Bit ADC (AD977) in parallel connected @ LPT using one DMM.
