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…
Armand,
From your description, it sounds like the DB bus is incorrectly connected and that the host is missing the two MSBs. This would explain a perceived 625mV range, the multiple rollovers and the fact that the max voltages is hitting code 4092 rather…
Hi Jari,
ADS7865 is a dual simultaneous sampling 2MSPS 12 bit device with 3+3 or 2+2 channels and parallel interface. Conversion time is as low as 406ns (13 clks at Fclk=32MHz). Full-scale Input range is +/-VREF; where VREF=2.5V; absolute input range…
Hi Tobias,
The overshoots you see may or may not be real - depends on how you have the board probed. If you have good (and short) ground leads with low capacitance probes, you may be seeing overshoot simply due to the switching speeds of the clock, the…
