PGA970: How to get the detailed PGA970 datasheet and Schematic / PCB library ?

user6558735

Part Number: PGA970

The PGA970 datasheet  downloading from TI.com is not  completely ，how  do I  get the full data sheet included the Pinout and Electrical Specifications 

We will use the SPI interface of STM32F103  to controll the PGA970 , and transeive data via WiFi , how to evaluate the MCU meeting the LVDT measurement ？

If simply implementing Current mode 4-20mA output , Do the EVM-PGA970  schematic meet the requirements?

When I download the PGA schematic/ PCB  library from Ultra librarian webpage,  it always display "Your Ultra Librarian download has encountered an error, please wait a moment and retry your request."

    Hello,

    The full PGA970 datasheet is available for download by request only. You can find the link to request the datasheet on the PGA970 main page. Under the heading "More Information."

    I'm not sure about the Ultra Librarian issue. It may depend on the format that you are looking for. In testing just now I was able to download the Altium symbol without issue. Is there another format you can import into your PCB layout software?

    The PGA970EVM schematic is a good starting point. The output circuitry is suitable for 4-20mA output with the correct jumper settings.

    Regards,

    In 4-20mA output application ，whether need I  develop the software  about M0 mcu ?  Can I resolve this application just using Hardware Developement ?

    To have a 4-20mA output that is driven by the LVDT input to the PGA970 you will need some firmware. The output DAC is controlled solely by the data written to the DAC_REG0_x registers. Without firmware the input data cannot be processed and then written to the DAC registers.
