Ah, I see your reasons... May want to check with that team (OPA team) but TI has a pretty strict obsolescence policy, so, production may go easily till that time... Anyhow, the same team can otherwise recommend something but we haven't tried it, so, you…
Hi Pradeepkumar,
MSPM0 L-series has no independent DAC module, so we need output COMP.DAC by OPA module. PA16 can be configured as OPA1_OUT, so I think it's OK. You can confirm Pin configuration in the datasheet or SysConfig.
You can refer to the SDK…
Hi Mori,
Yes, it also can do.
The tips is that you should set the OPA works as the buffer mode, so you should RTOP on the NSEL for this. Then the output will follow what you input in PSEL, which can be DAC8/DAC12/VREF.
B.R.

Hi Nicholas,
thanks a lot for the fast feedback.
So to understand from the post above is that you already have boards with the traces of LDO1 to the SD card domain of the SoC? To that affect, is the wrap wire populated and you're trying to avoid powering…
Hi team,
1. The biggest difference between a general resistor and AD5161 (variable resistor) is that there will be a pF-level parasitic capacitance to ground on both sides of the AD5161 resistor Pin, because the parasitic capacitance on both sides will…
Hi Nick,
Thanks for your quick answer. Is it possible to have the circuit design for the Spice software (to have the feedback capacitance value) or just a sreenshot of the design ? Is it a problem if the OPA856 spice model has only 5 pins ? (missing the…
Hi Harish-san,
OK, I understand that I_PK(dem) is the reference generated from the loop.
So, is it possible to determine the exact timing when output voltage sampling is triggered from the scopeshot?
How can my customer estimate the timing if the CS falling…
Hi
The backlight works fine. I have decided to write my own library with the help of the one I mentioned in this post. When using my code it does not seem to get stuck anywhere.
I thought it might be due to my clock and the library says set it to 8 MHz…
Hello Jack,
Power consumption numbers for each mode are given in the datasheet (Section 7.5). There are significant differences in current consumption between the modes. In addition, you can find a table in section 8 (Table 8-1), that tells you what clocks…
Part Number: OPA357 Other Parts Discussed in Thread: REF3030 , , TLV9101 , OPA310
Hello,
I'm using an OPA357AIDBVR (IC18) to buffer a REF3030 chip. Below I show all the circuits that have interface with the AVREF: The problem: the AVREF should follow…
