Part Number: PGA970 Other Parts Discussed in Thread: USB2ANY Hello. I have designed a circuit using the PGA970 and am using it connected to the GUI. However, I am unable to output a sine wave from P1 and P2. Is there an issue with the circuit configuration…
Part Number: PGA970 Hi,
I'm trying to create a communication between PGA970 and STM32H7A3 - Nucleo-144 through spi
this is my settings for Nucleo board:
static void MX_SPI1_Init(void)
{
__HAL_RCC_SPI1_CLK_ENABLE();
hspi1.Instance = SPI1;
hspi1…
Part Number: PGA970
We are using a PGA970 integrated circuit to excite the VDT sensor and read the voltages from it. However, we also need to read the phase information.
We found information on how to read the phase angle in the link below. But there…
Part Number: PGA970 Hi,
As I can see in the datasheet, there is no possibility of having more than +3 V on the AVDD pin. In my case, even with all the hardware recommendations from the datasheet, I can measure up to +5 V. Here is my schematic:
Is…
Part Number: PGA970 Hello TI Team,
I am currently developing a custom signal conditioning system using the PGA970 for LVDT applications.
We have implemented a dynamic generation system for the BPF and LPF coefficients, matching the values from the…
Part Number: PGA970 Hello,
I am currently working with the PGA970 and following the PGA970 Software User's Guide , which includes screenshots and references to projects created in Code Composer Studio (CCS).
However, I am having difficulty locating…
Part Number: PGA970 Hi,
I am currently bringing up a custom LVDT board based on the PGA970. I have successfully completed the first step: generating the excitation sine wave on the primary side.
Now, I am ready to connect the LVDT sensor to the device…
Part Number: PGA970 Hello,
This thread is a continuation of the previous discussion, as the original thread has been locked.
Setup Description
We are interfacing the PGA970 as an SPI slave with an STM32H5 acting as the SPI master. SPI timing and…
Other Parts Discussed in Thread: PGA970 HI, I'm using the PGA970 on a custom board (not an EVM) and configuring it via SPI from an external MCU (ESP32).
The DEMOD1 output remains 0 unless I manually write non-zero values to the DEMOD BPF/LPF coefficient…
