Part Number: ADS8684A
Hi Team,
I understand that DVDD(+3.3V) must be less than AVDD(+5V).
However, slew late of DVDD is high so DVDD higher than AVDD during 5ms.
Then, could you please let us know if you have any concern (device is broken / malfunctions etc.)?
Regards,

Part Number: ADS1262
I've been using the ADS1262 for a very early stage prototype (I have that mostly working). I haven't been overly concerned with calibration and power, as I was previously just trying to validate a general concept.
Now I need to narrow down how best to power the loadcell. Loadcells are typically spec'd for 0-10v, but the ADS is +/-2.5v or 0-5v. Can you point me to any resources for how best to handle this? Also, its a battery powered application, which will also power the microcontroller.
For background, my current iteration uses a 7.2v battery through a LM78M05 to provide 5v to the AVDD (pin 6) of the ads1262. That's mostly working, but I'm sure far less than optimal for the loadcell.

Part Number: ADS1278-SP
Hello TI experts,
I am using the ADS1278-SP in an application where part of the board has the AGND plane, and the other part of the board has the DGND plane, as shown in figure 11.2 of the datasheet. Half of the ADS1278-SP package will lie on the AGND side, and the other half will lie on the DGND side.
The ADS1278-SP, like the ADS1278, is equipped with a PowerPad for thermal management.
My question is, do I connect this PowerPad to the AGND plane, or the DGND plane?

Part Number: ADS1298R
Hello everyone!
I bought ADS1298R chip from TI for my project, not long ago. But erroneously I ordered BGA type instead of TQFB. As I have no experience with this type of chip, I can't solder it to my board. I searched on Google and youtube about soldering, but every time I get information about repairing, reinstalling or reballing BGA and like these other information. I'm making a circuit from scratch, so I need to prepare my circuit soldering in the new green plate. But I don't know how to do it.
Since then I have couldn't make my circuit board. :(
Can anyone help me with videos or other resources
thanks in advance.
Part Number: ADC161S626
Hello,
I am trying to send out the ADC value to my microcontroller(hercules) on SPI. The adc needs 18 clocks to push 16 bit data out but hercules has max word length of 16 bits. So I am doing 2 successive receives so that I get 2 16 bit words out then left shifting these by 2 bits to compensate for the 2 clock cycles. But I am not getting the exact reading on miso pin. Could you also help me with the math that I should be using for converting the obtained code to Analog voltage value. (I am using ADC in single ended operation mode)
Thanks,
Aditi
Part Number: ADS1298
Hi, Alexander.
Do we need add extra amplifier to ECG sensors signals before input them to ADS1298R.
As heart muscle signals in the range of 1-5mV, and input of the chip is 2,5 -5V
Or internal PGA will be sufficient
Why I skthis question, because I doubted after seeing block diagram below
Thanks in advance
Part Number: DAC43608
Hi
Device : DAC43608
If VOUTs are shorted to GND, Does the device have any risk of damage?
Customer is considering the following configuration.
Is there any problem?
They want to be under 0.5V when transistor on.
Short circuit current is 50mA(from datasheet). So they will select the transistor spec under VCE(sat) < 0.5[V] at this current.

Hi,
I am working with a customer using the ADC3242. The clock slips when moving from test mode to normal mode and the user is having to restart device. Is this behavior expected? What could be causing this behavior?
Thank you,

Part Number: ADS8698
Hello? I am a Ph.D. student in electrical engineering. I am currently trying to change the input voltage range using ADS8698.
Below is the link to the data sheet for the part I'm using. The figure below is the FSM illustration shown on the data sheet.
The following is how I programmed the FSM illustration. (I am currently using verilog.)
http://www.ti.com/lit/ds/symlink/ads8698.pdf
Connecting power to ADS8698 (I am using external power rather than internal power) automatically goes into IDLE state.
1. In sdi (command of 16 bits entered in ADC), enter the program resister command. This command includes setting the input range of the analog signal entering the ADC and how many channels the ADC will accept (Status: IDLE -> PROGRAM RESISTER).
I refer to pages 48 to 50 of the datasheet.
2. In sdi, enter the MAN_Ch_0 command. This command asks channel 0 to write the value. (Status: PROGRAM RESISTER -> MAN_Ch_0)
I refer to page 44, 47 of the datasheet.
3. Enter the no operation command (sdi = 0000 0000 0000 0000 000000) to continue to convert data entering the ADC to digital values under the same conditions
I refer to page 39 of the datasheet.
Please note that if I didn't do the first part of the above process, it would have been well done without an error. But when I added the first course, the following symptom was observed. (I think there is a problem with the number 1 sdi command I entered, or I skipped the necessary process.)
Symptoms: Regardless of the size of the ADC input signal, only one identical value is given (e.g. 000011000).011)
For your information, this ADC has a resolution of 18 bits.
Did I do anything wrong? The issues that I think are likely to be high are as follows.
1. Problems caused by configuring FSM too simply without using reset or standby or power down mode
2. The problem caused by not reading as much as write in process 1.
The program response command I entered is 0000 1011 0000 0110. (The eighth bit means write, 0 means read)
What's the problem?
Part Number: ADS1262
Hi there,
For our Pt-100 application we need to find a way to get an increased measurement current of 5mA. Using an on-chip IDAC is most convenient, but a single IDAC is limited to 3mA. So we would like to use both IDACs in parallel at 2.5mA. Does anyone have experiences in doing so? Are current sharing series resistors or even diodes mandatory? What value would be recommended?
Best regards
Simon

Part Number: ADS1262EVM-PDK
Dear Ladies and Gentlemen,
I want to integrate the evaluation board ADS126XEVM-PDK into my existing LabVIEW measuring program. The measuring program controls a motor controller with 4 connected linear stages and a nanovoltmeter. The linear stages move a measuring coil in a magnetic field, the induced voltage in the range of 1 to 3µV is measured by the measuring device. I would like to replace the Nanovoltmeter with ADS126XEVM-PDK evaluation board for test purposes. I programmed my measuring program in LabVIEW. The program works very well so I want to change as little as possible.
Is it possible to control the evaluation board ADS126XEVM-PDK via the USB port using the USBStyx driver without installing the ADCPRO program?
Where can I download the USBStyx Driver?
Which function does the USBStyx Driver perform?
Can I only install the USBStyx Driver or do I need other drivers?
Why do I need the "mmb0_driver_install_x86-v1.0.0.0.msi" driver?
Does the LabVIEW example program "ADS126xEVM-PDK Example GUI.vi" work without the ADCPRO program?
I ask you to answer my questions as detailed as possible and apologize in advance for my very bad English.
Yours very kind regards from Hamburg
Part Number: ADS131A02
Dear all
I would like to ask questions about clock source of ADS131A02.
1. According to Datasheet, the typical value of fCLKIN is 16.384MHz.
If a frequency larger than this value (for example, 20 MHz) is input, the conversion time is considered to be shortened.
Are there any other effects other than conversion time?
(Please let me know if there are any disadvantages when increasing the frequency.)
２．The data sheet shows that SPI SCLK can also be used as an external input clock. Furthermore, the frequency is in the same value range as fCLKIN. I think using SCLK is fine, but are there any disadvantages compared to using fCLKIN?
(If SCLK is used, if there are restrictions other than frequency, please let me know.)
Best Regards,

Part Number: TLA2024
I am using TLA2024 to measure differential voltage between AIN2 and AIN3 with following parameters:
ADDR - > GND - Slave address(48h)
VDD - 5V
I2C bus pull up resistor - 10k Ohm
I2C bus clock frequency - 100kHz
9th clock is too slow. Also, TLA2024 doesn't acknowledge, we get NACK on the 9th clock.
There's no response from the TLA2024 when I tried reading the config register.
Also, I can't write to the TLA2024's config register.
Please help me out.

Nishil Bhavsar
Part Number: ADS7882
What is the voltage range on the ADS7882 external reference input? For example could I use a 4.096V or 2.048V reference on the ADC to have the output correspond directly a decimal number i.e. 0.001V or 0.0005V or would I have to use a 2.56V reference to do so?
Thanks for any help!
Part Number: ADC12J1600
