Part Number: ADS127L01EVM
First I want to say sorry because I know it is basic questions, but my major is not electronics then I have some trouble.1) Is it possible to connect 2 analog inputs at the same time? because I saw 2 SMA jacks, or we must use 2 jacks for 1 input? 2) How can I connect it if my input come from photodetector with 1 bnc connector?Thanks you for your attention!
Hello Linh, Thanks for your post and welcome to our forum! 1.) Please check the schematics at the end of the ADS127L01EVM User Guide. The signals applied to the SMA connectors are routed to the input of a fully-differential amplifier. The output is applied to the ADS127L01 input pins and the decimal output code is proportional to the difference between AINP and AINN. 2.) You'll need to find a BNC-to-SMA adapter. The signal can be applied to J9 and the shield can be connected to J7. Install R72 with 0 ohms to short J7 to GND.

Not at all! Glad to help.
1) What does "installing R72" mean? Could I find a resistor and solder it to the module ?
Yes - you may install a 0-ohm resistor on the footprint for R72. We sometimes leave extra component footprints on the PCB for customers to modify and experiment with different configurations. Best Regards,
Hi Ryan,but 0 ohm resistor means just solder it together right?
