Part Number: ADS7253 Hi
In the datasheet the analog voltage the absolute min is -0,3 V and absolute max is 6 V.
The Nominal analog votage is 5 V.
I use this setup with 5 V already in an application.
Now I want to use it in another application but here…
Part Number: ADS7253
I could get one sample value(eg, current) with one request, as general application. Now I want to get two sample value(eg, current1, current 2) with one request(send SPI msg only once), so I could caculate the current = (current1…
Part Number: ADS7253 Other Parts Discussed in Thread: ADS7254 , ADS7251 Hi team,
My customer want to find the alternative GPN which can P2P replace the ADS7253IRTER as their second choice.
The Resolution should be 12 bits or better and sampling rate…
Part Number: ADS7253 Hello there,
I'm trying to interface SPI based external ADC "ADS7253 " with BF609 processor . What is operational max SPI clock frequency for ADS 7253 ?
Part Number: ADS7253 Hello There,
We are using ADC Part No# ADS7253IRTER. The ADC is connected to MCU/DSP processor on the SPI Port. The MCU/DSP processor support the standard SPI Mode 0, 1, 2 and 3. The ADC samples the data on SDI line and shift out the…
Part Number: INA240 Other Parts Discussed in Thread: ADS7253 , Hi,
Here is a customer design using INA240+ADS7253 as below. The sampling frequency is 10ksps, working common voltage is 48~72V. They found anti-alias filter(R30,R31,C17) influence the sampling…
Part Number: ADS7253 Hi,
Can ADS7253 use 1Msps for both of 2ch?
ADS7253 has 2 ADCs and can it use full sampling performance when 2chs are enabled?
Thanks.

Hi TI Team
I am using ADS7253IRTER chip for measuring the analog voltage. I want to use internal reference voltage for the ADC. Could you please tell me the steps for configuring the CFR, REFDAC_A, and REFDAC_B registers and readback…
Chi-Yuan,
After looking at the ADS8353 I don't think a native SPI mode(either the SPI or the McBSP in SPI mode) will get what we want, due to the clocking requirement and relationship to CS signal. I think the control of the CS needs to be handled…
Part Number: ADS7253 Hi all Would you mind if we ask ADS7253? It seems that there is the difference of input impedance in case of AINP < AINM and AINP > AINM. As the background of this question, if AINP and AINM are near value, it seems asymmetric behavior…
