Part Number: ADS7881 Hi,
Since isolation of 2500Vrms is needed between the digital module and the analog module , we use high-speed optocouplers - ACSL-6400.
The optocoupler drive the A/D Digital inputs and the optocoupler "Output Rise Time" is 35ns…
Part Number: ADS7881 Hello,
I am interfacing ADS7881 to my FPGA. Sampling frequency = 2MHz. I am writing SDC timing commands for Timing analysis for my FPGA design and I need the Input and Output delay values for all the pins of ADS7881. I didnt find…
Other Parts Discussed in Thread: ADS7881 , OMAP-L138 , ADS7881EVM Hi,
ADS7881 offers parallel interface, I am wondering if it's possible to interface this data converter with OMAP-L138 EVM using UPP ? What other options are available to interface this device…
You are correct, but since these groups are always doing devices for the next rounds of test equipment they always have to do better than anything you can buy. In HD work, source cancellation methods are normally used, one of the very few published references…
Other Parts Discussed in Thread: ADS7881 Hi Tom,
I am trying to scale ADS7881 outout but I couldn't
manage to do it. I inputed 1.25 VDC to adjust R25 to mid scale
but the code axis keep moving as I move R25. However, I adjusted R25 to
set the DC…

We have an ADS7881 converter that cycles continuously. We build up a voltage on a capacitor, which eventually trips a comparator, which causes CONST! to go low. When BUSY goes high,…
Other Parts Discussed in Thread: ADS7881 , AM3703 Hello-
Regarding the ADS7881 12b SAR. My cusotmer is trying to use it between a contact imagesensor and a AM3703 based SoM. His question:
"Is it safe to assume that the voltage that gets converted to…
Other Parts Discussed in Thread: ADS7881 The ADS7881 Specification, regarding the readout of the digitized data: The time for the DATA to be enabled onto the bus (td6) is 25ns maximum. The time for the DATA to decay from a disable (READ deasserts) is also…
