A single external resistor sets any gain from 4 to 10 000. Demo of the ina125 with a 50kg load cell on a breadboard. Excitation white.

The load cell output needed converting into a digital input using an aanalogue to digital converter adc which i covered in my previous post. We ve gotten the circuit to perform well with one load cell but are having issues getting the expected output with the other. The circuit from the data sheet can be seen below. The ina125 is a 16 pin dip dual inline package ic.

Pin 15 and 4 aren t connected for a start and there were a few other. The most difficult part will be connecting the load cell if a pin connector crimping kit is not available. The ina125 is a low power high accuracy instrumen tation amplifier with a precision voltage reference. Signal green.
