Part Number: ADS7250 Hello team,
Datasheet says ADS7250 need external VREF of 2.5V.
Is there any way to use this device without external VREF? I dont need psuedo differential input, single end input is fine for me.
Many of single end input ADC can use AVDD…
Part Number: ADS7250 Since SDO-A and SDO-B represent 2 the results of the 2 ADC, do we also need to use 2 SPI interface from MCU to get the results?
Besides, we are not quite clear about the configurations for AINM and REFIN. Since they are connected together…
Part Number: ADS7250 Tool/software: TI C/C++ Compiler Hello,
I'm trying to read data using an Arduino with this chipset, and can't seem to get clean data from SPI & SPI1 using the same SCK. I have no MOSI wired only MISO on SPI and SPI1 and…
Part Number: AM625 Other Parts Discussed in Thread: ADS7250 , Hello team,
I want to use AM625 with ADS7250, which is 2ch simultaneous sampling ADC. ADS7250 has 2 SDOs but 1CS because it has 2 ADC cores inparallel.
Also, ADS7250 need to be fed with 32 continous…
Part Number: ADS7250 Other Parts Discussed in Thread: ADS7253 Hi
I want to connect ADS7250 and F28377s via SPI
and i checked datasheet of ADS7250.. and I found 2-SDO line...
How two connect 2-SDO line with DSP ?? One SPI module has only one SPISOMIx…
Hi Eric,
Thank you for your post.
The ADS7250 is another option to consider which also supports pseudo-differential inputs and is pin-for-pin compatible with the ADS7253. Some key differences between the ADS7250 and the ADS7253 include:
Date rate: ADS7250…
Part Number: ADS7253 Other Parts Discussed in Thread: ADS7250 Hello:
ADS7253IRTET is out of stock， Would you please recommend other TI chip which is close to ADS7253IRTET in function. Pin to Pin is better，Thanks！！！
Hello Nicholas,
Thanks for your post.
The ADS7850 only needs /CS, SCLK, and two MISO connections (SDO_A and SDO_B). Based on Figures 10 and 11 in the reference design document, separate SPI ports in the MSP432P401R are needed to accommodate each SDO signal…
Hi Adi,
Yes, it is possible to extend this to achieve 3-phase voltage and current measurement. There are multiple ways of implementing three phase measurement using shunt and voltage divider.
1. If you are using low side voltage measurement, you can…
