Part Number: ADS7056 Other Parts Discussed in Thread: ADS7891 Tool/software: Hi,
I have selected ADS7056IRUGR as an alternative to LTC2313ITS8-14. However, ADS7056IRUGR has Latency.
Could you please introduce a product that meets the following specifications…
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…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
