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…
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…
I don't have a scope with me right now. WIll have to wait till next week.
How would you write code to just read one SPI input from ADS7250.
What I'm doing is setting up SPI on an Arduino like device and then manually toggle CS low where I then use…
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…
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…
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！！！
Part Number: ADS7254 Other Parts Discussed in Thread: ADS7253 , , ADS7250 Hi,
Due to the ADS7253IRTET's out of stock, I need to find alternatives.
And i want to use ADS7254 to replace ADS7253, because it's pin-for-pin compatible.
ADS7253 supports…
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…
Dear Vinay Agarwal,
I'd like to use the ADS7250 but in a single ended mode with a signal of 5V of swing (AVDD=5V)
Is it possible?
Can I, for example, put:
AVDD=5V
REFIN_A= 5V
AINM_A=GND
AINP_A= my input 0-5V
and work as Single Ended? …
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…
