PGA308 EVM Board

Other Parts Discussed in Thread: PGA308, PGA308EVM

Hi,

I trust you are doing well.

I have some urgent question as below and
I need your favor for soloving this matter.

We Already made PGA308 circuit external separately.

And We want to use this external PGA308 circuit instead of PGA308 inside of the PGA308EVM board.

So, could you let us know how we can do Calibration & OTP program by using the external PGA308 circuit through EVM board?

Thanks.

    In addition, our pga308 circuit module is consist of the bridge sonsor and the three wire output (Vs, Gnd, Vout).
    And the 1W is connected to Vout.


    Ie, Our module is same as the Figure 6-1 (Three-Terminal Module, Ratiometric, Voltage Output, Bridge Sensor Conditioning application) in the PGA308 user's guide.

    So, could you let us know how we can do Calibration & OTP program by using our external PGA308 circuit module  through the PGA308EVM board? (instead of the PGA308 module  inside of the PGA308EVM board)

    Thanks.

    The attached file shows several different ways that you can use the USB-DAQ-Platform to calibrate your sensor module.  Let me know if this helps.

    i'm so thanks for you great support.

    i will test it follow you attachment.

     

    i wanna Calibration & OTP program by using the external PGA308circuit through USB QAD board.

    I  can test the input and output signal through oscilloscope.

    so i follow the datasheet use Three-Terminal PGA308 Module.  connect VCC ONE-WIRE &GND

    but the software show "One Wire Time Out"

    How to solve it?

    Sorry, I can't answer your problem about "One Wire Time Out"

    I'm not full skilled about PGA308 test environment. and I tested it long time ago, so.. It's dim.  

    But, currently, I have no problem using PGA308,

    And It's on the cooking. So, I can't oprn the door.

    Please refer to the data sheet and the application notes.

    And check your test condition (like jump switch and configuration) the manual suggested. (maybe, the prblem is at this point.)

     Good luck.
