Other Parts Discussed in Thread: INA128, INA129
Hello I'm Jo from south korea.
I'm not good at English, so I appreciate it if you understand me.
I'd like to make ECG module with INA126 and Arduino Uno.
Arduino Uno can provide only single supply as zero to 5V.
So I wanted signal that swings 2.5V.
Before I make module, I tried to test INA126.
When I tried to test with dual supply, It worked well as I expected.
But with single supply, It didn't work.
The input was +/-100mV 1Hz sine wave, but I can't understand why the result was like that.
Q. Could you explain the reason why? and if the schematic is not proper for module, can I get some schematics related single supply?
Thanks for your time.
