Hello Nikhil,
I assume you are looking for temperature drift data for the ADS1231. This can be found in the datasheet under Input offset drift and Gain drift.
As an example, assuming you calibrate at 25C and then the system temperature is increased to…
Part Number: LMX1204 Tool/software:
I need to provide a clock to a large number of 4GSPS ADCs across multiple PCIe cards.
We have a bridge card that links the PCIe cards together this will distribute a low jitter low skew clock to each PCIe card.
28…
Other Parts Discussed in Thread: HSMC-ADC-BRIDGE , ADS4249 , ADS4249EVM Hi,
I'd like to ask for information about "HSMC-ADC-BRIDGE REV C".
Concretely, I need one about pins information.
Although I confirmed the schematic file about the product…
Ben,
Good to know that the PARTID and DIE_ID read-back values are actually correct.
I fully understand your point, about the sample code does not apply BQ79631 register settings other than what can be seen in its sys_main.c. However, our situation here…
HI Ross,
The Improved Howland Current Source with the OPA2191 should work well.
- You can use a low noise, low drift 5V voltage reference of your choice. The REF7050 has very low 1/f (low frequency) noise and very low drift (2ppm/C).
- On the Howland…
Patrick,
I will look into this for you. Did you order the HSMC-ADC-BRIDGE card? When you mention "Does not work" can you tell me what the issue was?
Regards,
Jim
Hello Rohit,
We no longer offer the ADS1230REF boards. As an alternative, you can use either the ADS1232REF (24b version with 2 input channels and multiple gain options) or the ADS1231REF (24b, single gain of 128, includes low side bridge switch).
We…
Hello Daveon,
Thank you so much for the reply!
I want to first correct a statement I made in my original post. I should not have said 4 PDM mic streams. While we do have 4 PDM mics connected, that are only occupying 2 Serial Audio interfaces on the ADC…
Hi Daria Kiseleva,
Typically a bridge is measured ratiometrically, where the excitation source for the bridge is the same used for the reference voltage. Then, any variation in the excitation voltage is seen equally in the input signal and the reference…
Hi Jim,
Thanks for the files.
We are planning to make a HSMC ADC Bridge board to support all 16 bit connection from ADC EVM to HSMC connector. Thus we need to have the board layout file to modify the design. The shared folder only contains the Gerber files…
