Part Number: ADS7052 Other Parts Discussed in Thread: DAC91001 , ADS7056 , OPA836 , ADS7046 Hello,
I would like to build up an ADC test environment that can achieve about 14 bit from 1.65 V to 3.60 V. So I choose ADS7052 as my develop tool.
The attached file…
Hi,
We are currently working on the issue of DAC regular glitch.
Previously using LM317 as a Voltage reference, now we are use the LDO (TPS79901) and Voltage reference (REF1933) produced by your company for adjustment.
Sincerely thank you for your reply…
Hi Kai,
My testing agrees with yours, the LM4132 does have an overshoot that can be minimized with capacitors but it will still exists. I would say the REF1933 and REF2033 do not have the overshoot just like you tested.
The 2.8mA of the REF1933 could…
Hi Marek,
Thanks very much for the reply. I'm aware of the usual use of the REF1933 as you described in the accompanying diagram. The output of my prototype circuit will be an A/D converter on an Arduino board with A/D input voltage limited to 3.3V, hence…
Bob,
It doesn't appear the REF1933 part is built into TINA's internal library.
The REF1933 does has a reference design in that part's product folder on ti.com. Open that reference design with TINA click on the macro, and copy-and-paste it from…
Hi Ran,
Welcome to the TI E2E Forums!
Please note that the ADS1256 can only take a maximum 2.6V reference, so the REF1933 will not work with this ADC, but you could use the REF1925. That said, I'll answer your question using the REF1933 as an example…
