hello.
I'm calibrating the PGA309 with a USB-DAQ board and I'm experiencing two problems
1. The output of PGA309 is 0.5-4.5V analog output, but when I use register R5 for clamping, the lower clamp can reach 0.21V or so.
But the upper clamp only goes up to about 4.04V. The range I want to use is 4.5V, and the upper clamp should be greater than the 4.5V operating value. For example, if VREF is 4.096V and R5 is set to HEX47, the output will have a lower clamp of 0.21V and an upper clamp of 4.02V. 2;
2. now with two USB-DAQ boards respectively set the jumper cap address 2F90, 2F91, parallel operation will appear 2F90 read and write no problem but 2F91 read and write will often unsuccessful situation, I made a copy of the Tio32.dll folder and renamed it for the use of the 2F91 thread.
I am looking forward to your reply! Attached are the EEPROM values for some products
