Part Number: PGA309
Tool/software:
I have a PGA309 board (called oriBoard), which is made by my collegue. It can work normally. The Schematic is showing below.
I made 2 boards with the same schematic, using the same bin file burned in the EERPOM, which…
I think I figured out what is the problem and it was about my I2C driver. I am not using the built in controller and I tried some other device that has a built in I2C controller and I can interface with the PGA309. I tried some changes in my controller…
Part Number: PGA309 Hi team,
Here are some of the issues one of our customers is experiencing, could you please provide some troubleshooting advice?
I'm calibrating the PGA309 with a USB-DAQ board and I'm experiencing two problems
1. The output…
Hi Kailyn,
Thank you for providing the schematic and captured waveforms.
The bandwidth of your circuit is limited to ~165Hz due to the large (47nF) capacitor placed between Vsj and Vout. This capacitor (C3) is in parallel with the gain-setting feedback…
Part Number: PGA309 Hi,
I use PGA309 to detect Strain Gage Bridge changes. In many projects conducted with PGA309, the Strain Gage Bridge supply voltage appears to be 5V. For this reason, Vin1 and Vin2 inputs will be 2.5V in a zero-strain state. The supply…
Part Number: PGA309 Does the PGA309 have an internal microcontroller that controls the I/O and coefficient calculation or is all of the "intelligence" in hardware? We are trying to determine if there is internal "firmware' or if it is all just…
Part Number: PGA309 Hi team，
A customer at the E2EChina Forum also needs this Multi-Cal PGA309 Software Source Code, but the download link in the Original question is no longer valid, where can he download it?

Part Number: PGA309 Hi Team,
Hope all is well!
Can you confirm that the PGA309 does not have any on-board firmware and that all of the logic it uses for thermal compensation is in hardware?
Thanks!
Connor
Part Number: PGA309 I have tested with a PGA309 with a real sensor in the oven. For the temperature measurement the internal one was configured. I assume that this is also a diode where the forward voltage changes with the temperature change. The measurement…
Part Number: PGA309EVM-USB Other Parts Discussed in Thread: PGA309 , XTR117 ,
Hello,
I designed the circuit board in figure-2 using PGA309 and XTR117. I calibrated the circuit board using the PGA309EVM-USB DAQ platform. I use a strain gauge with 1kohm internal…
