pinko @ blog.exrockets.com wanted to test some cheap load cells so he decided to build his own load cell amplifier. He writes:
Both IA are Rail-to-Rail, single or dual power supply instrumentation amplifiers, however with different standard pin-outs. The gain is set by RG. RR1 and RR2 and CR form a voltage divider that could be used to offset the output signal. If no output level shift is desired then RR1 and CR should be omitted and RR2 should be a 0R resistor.
