Part Number: LM27762
Tool/software:
Hello,
I am evaluating if the LM27762 can be used as a bipolar voltage souce for an ADCs AVDD/AVSS.
The LM27762 is fed by a 3.3 voltage supplly which als feeds the DVDD of the ADC.
Some reference designs and…
Hello Bryan,
thank you for your reply.
Regarding your questions:
The power is supplied by an external system. There are different legacy versions of this system, which do supply different voltages ranging from 6 to 12V. The system I am designing…
Emil,
I'm not too familiar with all the options for the power supplies, but I had envisioned something like the following:
Here, the battery is dropped down to 3.3V by an LDO used for the microcontroller and the digital supply for the ADC. Then…
Hi Jimmy, Thanks for your post and welcome to the forum! I looked around a bit and have not been able to find the files online. Unfortunately the gentleman who designed the EVM is out of the office until January. The best I can do for now is this TI Design…
Hi Darren
I would say you are mostly correct in your assessment. However, consider that the AVDD supply is also connected to the PGA and internal reference. The noise may or may not be filtered out as expected. The modulator is multi-order and should…
Hi Wael,
I support the ADS124S08, but I do not directly support TI DC-DC converters. You would have to ask specific questions regarding the TPS61291 on the Power Management forum. As far as recommendations, all I can really say for sure is some customers…
