Part Number: PGA300 The PGA300 datasheet describes a 4-20 mA application. However, I cannot see any way to trim the output zero and span using multiturn potentiometers.
I'd be grateful if you could suggest a solution.
Hi Ed,
If it is already set as 1 that is the ideal setting. If it were higher than 1, then it would be useful to set the analog PGAIN to a higher value to avoid the need for additional digital gain.
Let me look into this a bit more and get back to you…
Part Number: PGA300 Hello there,
I'm working on pressure sensors and I've seen TI's very nice ICs. One of them is the PGA300.
My question will be as follows, in the application notes and reference designs, I have seen examples that give more…
Part Number: PGA300 0-10V output application, during DAC calibration,
766=0V with reading 1.47V, it should be around 0V
1800=5V with reading 4.76V, it should be around 5V
2700=10V with reading 5.45V, it should be around 10V
DAC Gain = 10V
Thanks!
P.S…
Part Number: PGA300 Hello,
I couldn't reply in the previous thread, so I created a new thread.
> Above the normal lower value, and below the normal upper value the DAC will respond based on the input and your calibration coefficients. Below the…
Part Number: PGA300 Hello,
I calibrate PGA300 with EVM and GUI.
I have a problem with calibration, so I would like some advice.
Until a while ago, I was able to calibrate without problems.
When I was conducting an accuracy verification test after…
Part Number: PGA300PGA300, 4 to 20 mA mode, DAC Code Calibration:
When read and write DAC code
1) when 4 mA, reading was always very close to 4 mA
2) when 12 mA, reading was always very close to 12 mA
3) when 20 mA, sometime reading in amp meter was…
Part Number: PGA300 Hello,
I don't know how calculate AD value of PGA300 EEPROM from PGA300 GUI voltage value. I would like to write AD value to PGA300 EEPROM by OWI communication that I prepared instead of GUI. The following are the items I want to attempt…
