Part Number: PGA970 Hi Team,
We have been using PGA970 for LVDT. It was working fine, generating primary excitation and getting the digital values of two secondary's. But suddenly the EVM stopped working and EVM is not generating any primary excitation…
Part Number: PGA970 Hello!
I've looked though multiple posts about no waveform output and have tried all of the suggestions. I can tell all voltage rails are correct, I can write the waveform to RAM from the ADC settings tab and read it back in the Data…
Part Number: PGA970 Hi Team,
We had installed PGA970 GUI and necessary supporting run time license from NI. We have USBTOANY Module interfacing to PGA970EVM and PC. When we give supply (3.5VDC) to VDD, no excitation signal appearing on P1 & P2. All jumpers…
Part Number: PGA970 Hi Team,
Customer is using PGA970 for LVDT sensors. They are using TI software for 3-wire and 5-wire connection.
In that software a 4-wire AdcMode is defined but cannot be used further.
Can 4-wire be supported via software?
Regard…
Part Number: PGA970 Hello,
I need to develop 3-wire LVDT with programmable. I saw PGA970 chip. I don't have full datasheet. Can i connect 3-wire LVDT on PGA970, IF yes how i can connect? Can i use cascade method for multiple chip configuration. …
Hi to all,
I solved my problem with GPIO2 as an input, I just replaced the Chip with new one (was really hard to remove and solder the new chip, but my risk worked ok). I think this pin was defect, and some other options did not work normal.
Wish you…
Part Number: PGA970 Hi TI,
I want to test the PGA970 EVM, but there is error message pop up every time I open the GUI application. Please refer attached picture for the error message. Kindly please advise.
Thank you.
Best regards,

Hi,
as I already said, when I ran the debugger, "interrupt void ADC_Handler(void)" did not execute, after running the debugger when nothing happened I Paused the debugger (Suspend) then I reset the PGA970 through the "CPU Subsystem Reset" or…
Part Number: PGA970 Hi Team,
We are trying to generate Vrms for Primary winding of LVDT. P1 and P2 are directly link to P1A and P2A through jumper settings. The configuration screenshot of GUI as below:
Through this we are able to get 1.25Volts Peak…
Part Number: PGA970 Hi Team,
We are trying to get AC excitation for LVDT . On primary P1A we are getting sine wave in PGA970GUI waveform generator. On TP71(P2A) the Sine wave is not appearing . Could you please help me to find a solution for getting Sine…
